13 (Number)

13 is a number.

Origin
On Friday, Smarch 13th, 1313, a bunch of medieval peasants realized that there was no number between 12 and 14. What a terrible mistake they had made. With the invention of 13, people were constantly spilling salt shakers and breaking mirrors. Nothing unlucky happened, but it wasted an awful lot of salt and glass. That shit's expensive, yo! Especially for a medieval peasant!
