Giraffe

A man goes into a bar with a giraffe, they both get a couple of rounds in. When they get up to leave they're extremely drunk and the giraffe passes out and falls over. The man opens the door, about to leave by himself, when the bartender stops him suddenly and says, "Hey! You can't leave that lyin' there!"

The man turns around and slurs, "Don't be silly, that's not a lion, that's a giraffe!"
