Evil garden gnomes (wait for it...)
And on a totally unrelated note, HumorFeed member Utterpants claims to have captured an evil garden gnome. (It wasn't mine, thanks for asking.) Now, being the shrewd satirists they are, you'll be given the chance to pay a ransom, as a bid on the omnipresent auction site eBay. The bidding starts April 3rd, and in all seriousness, it's to aid Amnesty International. We'll post the link to the bidding page when it goes live.
