1. Six
   Two
2. Four
   Three

This one catches out many, many people. Why? Well, it's because three would immediately jump into your mind. But if you read the question carefully ... fish can't drown, can they? So, you would still have six left!

1. On the left
   In the middle
2. On the right
   In Washington, D.C.

OK, so that's not too tough. Notice we never say the red house is left of the white house but left of the house in the middle. On a side note, did you know that the White House is well over 200 years old? It was completed on October 13, 1792.​

1. A fire to warm you up
   The stove
2. The match
   None of the above

Although you need to light all the other things to get warm and fill your belly, you won't light them if the match is not lit first. But you knew that, right?

1. 5
   6
2. 9
   Clive

Well, you are probably kicking yourself if you got this one wrong. But don't feel bad. People just skim over the question and think it is an easy one. But the answer is in the question. Did you miss it? Yes, it is Clive!

1. 10, maybe they missed
   Nine
2. Poor pigeons
   0

First of all, no one should be shooting pigeons but this is a hypothetical situation just for the purpose of a brain teaser. If someone shot one pigeon, well then nine would be left. But they wouldn't be sitting on the wire anymore. They would have flown away after hearing the gunshot.

1. 32 hours
   18 hours
2. 20 hours
   Zero hours

You got this one, right? Read the question carefully. We didn't say how long it would take one man to build another house. And for that reason, there is nothing to build. The eight men already finished the job, so therefore, zero hours.

1. Are you looking at me?
   Between us, something smells
2. You are an eyesore
   Aye, Aye!

This is an old brain teaser but certainly a good one. And, of course, between your two eyes, you would find your nose. Did you know lungs do not like air that is dry? That is why you should breathe through your nose. ​It will help to add moisture and humidity to the air before it enters your lungs.

1. Yes
2. No

OK, let's think about that for a second. His widow's sister? Why not? Well, there is the small problem that he is actually gone. Gone where? He slipped the mortal coil; he is dead! Read it again, his widow's sister. The word widow is the dead giveaway (so to speak)!

1. 100 pounds
   1 ton
2. 300 pounds
   None

Yes, none. When digging the whole, you would have placed the earth or dirt you removed from it on the side. If you put it back in the hole, you wouldn't have gotten very far. I can't be a hole if still has dirt in it.

1. At the bottom of the hill
   East of the tree
2. West of the tree
   On the ground

Wind speed is going to do little to affect where an orange will fall when it drops from the tree. And there is no mention of a downslope or hill. So the orange will fall on the ground!

1. Ton
   Metal
2. Piles of wood
   A car

This is a classic word brain teaser. Did you get it right? It's always the best policy with brain teasers not to jump to the first answer that looks correct. So, the answer is ton. Sure, that's heavy. Now reverse it? And there you have the "not." Clever, hey?

1. 12
   35
2. Six
   19

Twelve seconds? Yes, that is correct. "But how can that be?" you ask. Well, it is simple really. The 2nd of January, 2nd of February, 2nd of March, and so on until we get to December. Twelve seconds!

1. Two hours
   One and a half hours
2. One hour
   Half an hour

I bet you math whizzes got this answer correct. And yes, it is one hour, not one and a half hours. Why? If you take the first pill at 10, the second at 10.30 and the third at 11, then only one hour has elapsed.

1. An infant
   A dinosaur
2. A clock
   Unhappy fans at a music concert

Yes, a clock has hands, but they certainly can't clap. They can do something else a human hand and finger can do ... and that is the point but only at the time! Clapping, or applause was thought to have started with the Romans.

1. Throw it as far as you could
   Use a boomerang
2. Throw it up in the air and catch it
   None of the above

Throwing a ball in the air and catching it is the simple way to have it reverse its direction and come back to where it started. And it's all thanks to gravity because without it, the ball would keep​ on traveling. We would also float. Wait, how cool is that. Damn you, gravity!

1. Donald Trump
   Mitt Romney
2. George W. Bush
   The same as it is today

Although the president in 2008 was Barack Obama, the first African-American President of the United States, his name then was the same as it is today. You got this one right, didn't you?

1. 300 pounds
   150 pounds
2. 80 pounds
   Meat

Well, we would need a scale to see how much the clerk clocks in terms of pounds but you can rest assured that every day, he weighs meat! Another classic brain teaser that kids will love!

1. Unicorns
   W
2. A pot of gold
   A lake of water

If Irish mythology is to be believed, its a pot of gold and a possessive leprechaun that you would find at the end of every rainbow. But in the world of the brain teaser, it is simply the letter "w."

1. Yosemite Falls
   Niagra Falls
2. Tugela Falls
   Angel Falls

Despite the fact that it was not discovered, Angel Falls would still have been the highest waterfall in the world. Nothing was bigger, so therefore, discovery or not, it was the highest. Incidentally, Angel Falls is 979 meters high.

1. 12
   14
2. 13
   18

That's right. Apparently, bakers are the charitable sort, because a baker's dozen is 13. Actually, they made the extra one in case something went wrong. If it did, they then had a spare with which to replace the problem item.

1. Food
   A secret
2. Happiness
   None of the above

Isn't this so true? How many times have you been told a secret that you just want to tell someone? Every single time, right? And when you do, it's no longer your secret. Plus, the person who told you is probably going to get mad that you shared it. A secret is only a secret if you keep it!

1. February
   March
2. April
   All of them

Although February is a month with just 28 days, or 29 when it'​s a leap year, if you think about it, all the months of the year have 28 days. Did we catch you with that one or not? You would be surprised how many people get it wrong.

1. Eat spinach
   Buff up at the gym
2. Call a superhero
   Where are you going to find a giant with one hand?

So true! Giants are hard to find these days and giants with one hand even more so. Try this one on your kids; they will love a classic brain teaser like this!

1. A state law from 1797 forbids it.
   Its too far to move a body.
2. He is still living.
   None of the above

OK, so this is a brain teaser classic! And you should have gotten it right, right? Certainly,​ there is no law from 1797 that doesn't allow someone from New York to be buried in California. The simple reason it cannot be done is that the person is not dead!

1. Don't stop dancing
   Red Bull
2. Strong black coffee
   Sleep at night

Imagine not sleeping for five days and nights! Yawn! It makes you tired just thinking about it. But back to the brain teaser. If you're not sleeping during the day, you certainly will be sleeping at night. So, no problems there.

1. 2000
   1921
2. Every year
   1971

For some reason, our brains think that Christmas and New Year's Day are separated by two different years. But that is because we celebrate Christmas, and then, New Year's Day comes in the following year, just a week later. We forget we already had a New Year's Day in the year in which we just celebrated Christmas, however.

1. Yes
2. No

Yes, there is even a 4th of July in North Korea and every other country in the world. It's a day in July and it happens annually. But the holiday of the 4th of July as celebrated by Americans happens only in the United States.

1. Mirror
   Egg
2. Glass
   None of the above

I bet you know a few people who would be lost without their mirror. Mirrors, as we know them today, are silvered-glassed and were first invented in 1835 in Germany by a chemist named Justus von Liebig.

1. They were eating doughnuts
   They had their backs turned
2. He was walking
   They let him off the hook

Although it's possible that they may not have seen him, or they were too engrossed in their doughnuts, at no point did we say he drives his truck past them. So by logical deduction, we can say he was walking and that's not an offense.

1. Your body odor
   Fingerprints
2. Dirt from your shoes
   Memories

Isn't it amazing that every single person in the world has unique fingerprints? Just think about it. There are 7.7 billion people in the world and each of them has their own fingerprints, never to be repeated. The first time fingerprints were used to solve a crime was in 1892 in Argentina.

1. Cat
   Mouse
2. Fence
   Car

OK, this brain teaser only works if a fence really goes around the entire house. What if it is only on the front of the house? Just kidding! It's a great little brain teaser, especially for young kids.

1. A ball
   A cold
2. Water
   A balloon​

The general saying in English when you get the sniffles is to say that you "caught a cold." Now, you cannot throw that at someone, can you? The common cold can be caused by 200 separate viruses.

1. Gold
   Feathers
2. They weigh the same

Although you would need plenty more feathers than gold to make up 100 pounds, they weigh exactly the same. Not sure what you are going to do with all those feathers!

1. Fingers
   Shadow
2. Toes
   Soul

As Cat Stevens once said, " Oh, I'm bein' followed by a moon shadow, moon shadow, moon shadow." Certainly, if there is a strong source of light around, then we are going to have a shadow. But why? Well, any object through which light cannot pass forces the light around it and essentially, that is how a shadow is cast.

1. A lottery win
   A late train
2. Tomorrow
   The check in the mail

Well, it just makes sense, doesn't it? By the time tomorrow comes, it has become today. And then, there is another tomorrow, but it's today again. So, does tomorrow even exist? Think about that!
