Yellow Pig Day is a celebration of the number 17.
The mascot for this day is a yellow pig with 17 eyelashes, 17 toes and 17 teeth.
It is rumored that the pig was chosen because David Kelly collected pig figurines.
People wonder if he had 17 pigs and if the day should be called Yellow Pigs Day instead.
Yellow Pig Day is now a popular annual celebrated at several universities.
