Fun Observances 

 Yellow Pig Day

July 17 is Yellow Pig Day. Despite its name, the day is not a celebration of the porcine world, but a celebration of the number 17.

The unofficial holiday was created in the early 1960s by Princeton mathematics students, David Kelly and Michael Spivak, while working on the special properties of the number 17.

It is unclear why the day was called Yellow Pig Day or what a yellow pig has to do with the number 17, though legend has it that it is in reference to David Kelly's collection of yellow pigs. The mascot of the holiday, the yellow pig, has 17 toes, 17 eyelashes, and 17 teeth.

A Number With Special Properties

17 is a prime number that has significance in mathematics. It is the sum of the first four prime numbers - 2, 3, 5, and 7. A prime number is a number that can only be divided by 1 and by itself. Several studies have shown that when people are asked to choose a number between 1 and 20, a majority of people choose the number 17.

17 is not always a special number. In Italy, for example, 17 is considered to an unlucky number.

How to Celebrate?

  • Gift the mathematicians in your life marzipan Yellow Pig candies or yellow pig plush toys.
  • Do 17 acts of kindness during the day.
  • Sing Yellow Pig carols.

Did You Know...

...that the fear of the number 17 is called heptadecaphobia.

At the nudist colony for communists, two men are sitting on the front porch.

One turns to the other and says, "I say, have you read Marx?"

The other replies, "Yes … I believe it's these wicker chairs."

An old farmer is inconsolable after his dog goes missing. He takes out an ad in the newspaper,

but two weeks later, there’s still no sign of the mutt.

“What did you write in the ad?” his wife asks. “

‘Here, boy,’ ” he replies.

A panda walks into a bar and gobbles some beer nuts. Then he pulls out a gun, fires it in the air, and heads for the door.

"Hey!" shouts the bartender,

but the panda yells back, "I'm a panda. Google me!"

Sure enough, panda: "A tree-climbing mammal with distinct black-and-white coloring. Eats shoots and leaves."

This cowboy walks into a bar and orders a beer.

His hat is made of brown wrapping paper, his shirt and vest are made of waxed paper, and his chaps, pants, and boots are made of tissue paper.

Pretty soon they arrest him for rustling.
