15 (Number)

15 is a number.

Origin
15 is a number that originated when someone was feeling certain... urges. Kids, you'll find out what those are when you're older! He wanted to make a 69, but thought he'd get there by adding 6 and 9. He goofed up, making 15 instead. To be fair, though, he made the first fifteen, which is pretty impressive. Did you know that when you write out 15 as a word it displays as "fifteen?" The English language is incredible!
