Is this hilarious or what?

So yesterday me and my friend were talking about the world's highest highdive (don't ask me why, it was on Jack), and my other friend asked "How high IS the world's highest highdive?" and the one who was talking about it said "As high as Paula Abdul." and everyone started laughing, and I didn't get it, and I said "But she's short!" and then I got it. lol, I'm such a blonde...
