A Bottle and a Cork

A bottle and cork cost $1.10. If the bottle costs a dollar more than the cork, how much does the cork cost?

Most people guess 10 cents, but $1 more than 10 cents is $1.10, which would mean the total cost would be $1.20, not $1.10.

The correct answer is 5 cents. If the cork costs 5 cents, then the bottle costs a dollar more, or $1.05, making the total cost $1.10.

What Has Roots Nobody Sees?

What has roots that nobody sees,
Is taller than trees,
Up, up it goes,
Yet it never grows?

A Red Robe and Staff In Hand

I wear a red robe,
With staff in hand,
And a stone in my throat.
Cut me and I weep red tears

What am I?

A cherry

There are a few other variations of this one:

As I went through the garden gap,
Who should I meet but Dick Red-cap!
A stick in his hand, a stone in his throat,
If you’ll tell me this riddle, I’ll give you a groat.
(Said to be the lyrics to A Cherry)

I slipped down a slippery gap,
Found a man with a red cap,
He had a stick in his back and a stone in his belly,
Riddle me this and I’ll give you a penny.

At Least One is a Boy

A couple has two children. At least one of them is a boy. Assuming the probability of having a boy or girl is 50%, what is the probability that both children are boys?

If you answered 1/2, you’re not without comrades, but the generally accepted answer by statisticians (though not without debate) is 1/3. This is because there are four possible combinations: boy-boy, boy-girl, girl-boy and girl-girl. Since we are told one of the children is a boy (but we don’t know if it’s the first or second child), we can rule out the girl-girl combination, leaving three remaining options. Only one out of 3 is boy-boy, so we get a 1/3 chance.

This is a well-known problem known as the Boy or Girl paradox. The other variation is this brain teaser.

Only Hides in the Unwound

What can be seen but never found that only hides in the unwound?

Relaxation. You can see when someone is relaxing, but no one can remain completely relaxed forever. You can relax more easily as you learn to unwind.

Four Legs and a Foot

What has four legs and a foot, but can’t walk
And a head but can’t talk?

A bed. The foot of the bed can’t walk and the head of the bed can’t talk. It’s probably a good thing that beds can’t walk and talk. Just think of where they’d go and what they’d say…

The Hand of the Princess

A wise king devised a contest to see who would receive the Princess’ hand in marriage. The Princess was put in a 50 x 50 foot carpeted room. Each of her four suitors were put in one corner of the room with a small box to stand on. The first one to touch the Princess’ hand would be the winner and become the new King.

The rules were the contestants could not walk over the carpet, cross the plane of the carpet, or hang from anything; nor could they use anything but their body and wits (i.e. no magic, telepathy, nor any items such as ladders, block and tackles etc). One suitor figured out a way and married the Princess and became the new King. What did he do?

Asked the princess to touch his hand.

The Shortest Sentence In the World

What is the shortest sentence in the English language?

Jelly donuts (ice cream is better)

The typical answer to this is “I am,” but some argue that it’s not a complete sentence. However, if someone asked a man named Rupert if he was Rupert, he could reply, “I am” and it would make a complete sentence in my book.

But that’s not the whole answer. There is an even shorter sentence using an imperative with an implied subject (how’s that for an English terminology-filled sentence?) With “Go,” the “you” is implied. For example, if your wife wanted you to go with her to pick up some donuts and you were busy, she might say, “I really want to get some donuts, I’m starving!” and you might reply, “Go!” The implication being you never wanted to get donuts in the first place because you like ice cream more anyway and if you’re busy you’re probably doing something worthwhile and important and can’t be disturbed for such trivial matters as acquiring sweet pastries with holes in them, no matter how much of a waste of time your wife says your pursuits are. In short, “Go” is the shortest sentence in the English language that also has the longest implied meaning. Do you want to get get some ice cream? Go!

Ava pointed out in the comments that No is another viable alternative.
