You know those back-of-the-book caption contests in the New Yorker where they draw something and you're supposed to come up with a clever bit of word play to win fame and a signed version of the cartoon?
If you're as bad at it as I am, maybe you'd do better with Radosh.net's anti-caption contest.
Take this drawing....
You could come up with something wickedly funny, or you could come up with this:
"Five more minutes, and I get the shoe."
Now that's funny.
