If you're gonna watch this show, you know what to expect; sex jokes, people getting lit on fire, rock opera's about child rape, and other insanity that's more fit for late night Cinemax than prime time cable. In any event, the show is still hysterical in its pure craziness and great deliveries from the principal cast.
This episode, however, really took it to another level I think. Just take a look at the title of the episode. "Who Pooped the Bed?" I mean, you can't make this stuff up, you really can't. The episode revolves around the gang trying to figure out who took a crap in Frank's bed. In the end, Artemis, a chubby girl who occasionally pops up on the show, solves the mystery in a "Clue"-like manner via Tim Curry showing us multiple possibilities of who did it and why.
The ending is just so insane, and over the top, its an instant classic. A must for any "It's Always Sunny" fan.
