Some days, the only thing that gets me out of bed is the fact that it's my birthday. Happy birthday to me: I'm 11,515 days old today.
By the way, I must've netted about 20 chicks purely by telling them it's "my birthday", then following with "I'm XX,XXX days old. Happy birthday to me!"
It started from a game a chick and I played. Basically, we tried to outdo each other for coming up with (ridiculous) reasons to have a party. There were so many: The "It finally snowed!" party, the "I got done with work early today" party, the "I found 10 dollars in my coat pocket" party... but I came up with the mother of all excuses, and won the little game.
