Fiona's Fur

Alright, listen up, buttercup. The joke asks what's green and furry, and the punchline is Fiona from "Shrek". Get it? She's an ogre, they're green, and... well, she ain't furry, that's the joke, you nimrod! Also, the movie Shrek came out in 2001. You probably don't even know what year that is, you dummy.
