Wolves and Owls

You are in the woods with owls and wolves. There are 22 eyes and 32 legs. How many owls and wolves are there?

5 owls and 5 wolves, (not 6 owls because 2 of the eyes and legs are yours).

2 * owls + 2 * wolves = 20 eyes
2 * owls + 4 * wolves = 30 legs
owls + wolves = 10 eyes → owls = 10 – wolves
owls + 2 * wolves = 15 → 10 – wolves + 2 * wolves = 15 → wolves = 5
owls + 5 = 10 → owls = 5

Thanks, You’re Fired

A man is leaving on a business trip and stops by his office on the way to the airport. The night watchman stops him and says, “Sir, don’t take that flight. I had a dream last night that your plane would crash and everyone would die!” The business man cancels his trip and sure enough, the plane crashes, killing all the passengers. The man gives his watchman a $10,000 reward for saving his life, then fires him. Why?

Because his night watchman was sleeping on the job.

Winning at Wimbledon

As a result of temporary magical powers, you have made it to the Wimbledon finals and are playing Roger Federer for all the marbles. However, your powers cannot last the whole match. What score do you want it to be when they disappear, to maximize your chances of hanging on for a win?

It sounds obvious that you should ask to be ahead two sets to love (it takes 3 out of 5 sets to win
the men’s), and in the third set, ahead 5-0 in games and 40-love in the sixth game. (Probably you
want to be serving, but if your serve is like mine, you might prefer Roger to be serving the sixth
game down 0-40 so that you can pray for a double fault.)

Not so fast! These solutions give you essentially 3 chances to get lucky and win, but you can
get six chances—with three services by you and three by Roger. You still want to be up two sets
to none, but let the game score be 6-6 in the third set and 6-0—in your favor, of course—in the
tiebreaker.

Credit goes to Peter Winkler for creating this.

Which Are True and Which Are False?

A. When a car is driven forwards the wheels rotate counter-clockwise.
B. If a clock is put forward 1 1/4 hours the minute hand moves through 450°
C. When a clock reads 4.10 the acute angle between the hands is exactly 60°

A. False – The near-side wheels rotate counter-clockwise, but the far-side wheels rotate clockwise.
B. True
C. False – The acute angle is a little more than 60° because by the time the minute hand reaches 10, the hour hand will have moved slightly past the 4.

Calm and Cool Among Tumult and Fury

I remain calm and cool among tumult and fury,
I hide treasures and creatures you could hardly fathom,
I will crush those I welcome in deeply,
I am dark yet beautiful.

What am I?

Underwater in the deep ocean. Even when storms brew, the water deep below the surface is calm and cool. Thousands of treasures have been lost in sunken ships, and amazing creatures live at deep depths of the ocean. At extreme depths, the pressure is crushing. It is extremely dark deep in the ocean, yet also beautiful.

Hear a Lot, Say a Lot

I hear a lot
And I say a lot
Few ever look for me
And even fewer ever hear me
I hide in plain sight
Whether its day or night
To help is all I want
But most like to bend me
And as if they had a wand
Never again shall anyone find me
They do this to control
Without realizing the high price of a soul
But when I’m least expected
They’d rather be protected
For there shall be no place to hide
What am I?

The truth.
