Armageddon!

"I pushed a cardboard tube up his rectum and slipped Raggot, our gerbil, in," he explained. "As usual, Kiki shouted out 'Armageddon,' my cue that he'd had enough. I tried to retrieve Raggot but he wouldn't come out again, so I peered into the tube and struck a match, thinking the light might attract him. In retrospect, lighting the match was my big mistake.

Read all about Raggot, the Rectal Rodent, and be sure to listen to the hilarious sound file too. (It is an urban legend, though...) Oh man, I'll never be able to hear someone say 'Armageddon' without bursting into laughter again...
