Four Colored Balls in Gym Class

Four different-colored balls are being used in a gym class activity – blue, red, yellow and orange. Each student must hold two different-colored balls, but no two students can have the same two colors (for example, only one student can hold the blue and red ball).

How many students can play the game?

Six. If you prefer math, you can calculate it as 4 combination 2

4! / (2!)^2
24 / 4 = 6

Or you can work it out manually:

1. Blue Red
2. Blue Yellow
3. Blue Orange
4. Red Yellow
5. Red Orange
6. Yellow Orange

A City in the Twilight

Half-way up the hill, I see thee at last, lying beneath me with thy sounds and sights — A city in the twilight, dim and vast, with smoking roofs, soft bells, and gleaming lights.

The Past (Longfellow).

Why doesn’t a mountain covered with snow catch cold?

Because it has a snowcap. ;) I know, it was more joke than riddle, but I found it amusing.

Enjoyed By Some, Despised By Others

I am enjoyed by some, despised by others. Some take me for granted, some treasure me like a gift. I last forever, unless you break me first.

Marriage.

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.

I Can Sound a Gong

I’m in bowling and baseball,
For better or for worse,
On a match (but not the sporting kind),
I can sound a gong,
And I’m gone.

What am I?

Strike.

A strike in bowling is good. In baseball it’s good for the pitcher but not for the batter. You can strike a match to light it. When the clock strikes one a gong sounds and when you strike a paragraph, it’s gone.
