Did You Know?


Clyde has both a colostomy and is missing a testicle. See more »


Mr. Mackey comes on the intercom and says that Clyde couldn't possibly have been the one that defecated in the urinal because he had a colostomy at age five. Yet in South Park: Marjorine, after the boys steal the future-telling device from the girls' slumber party, when Clyde strips off his clothes and is showered off he has no physical sign of a colostomy (i.e. stoma in the abdomen).

Joe Hardly: Hmmm. Who would benefit from two buildings dissapearing?
Frank Hardly: Oooh. Oh, I just started getting a clue.
Joe Hardly: Really?
Frank Hardly: Yeah, I'm totally getting a clue.
Joe Hardly: Oh. Oh, thats giving me a clue. Yea-Yeah I've got a raging clue right now.
Frank Hardly: Mine's pointing to the left.
Joe Hardly: Oh, Frank, seriously, I have such a raging clue right now, I think we better follow it.
Frank Hardly: OK, lets follow your raging clue.
[both exit]
Randy Marsh: God speed.

Pretty good, probably liked it less after watching the excellent "make love not warcraft"
23 September 2008 | by (Canada(Montreal,Quebec)) – See all my reviews

Mystery Of The Urinal Deuce is a pretty funny episode.Watching it a second time, I enjoyed it more.I didn't care for it much the first time because I was completely blown away with the previous "Make Love Not Warcraft" episode.THis episode is pretty good, has some very funny moments and is another example of spoofing current events, but it's definitely a notch down from the previous episode.Cartman thinks 9/11 is a conspiracy and Kyle tells him its not true.So Kyle and Stan set out to find out the truth but then uncover a whole web of lies and conspiracies.Meanwhile, Mr Mackey tries to find out who took a crap in the school urinal.Pretty good episode in my opinion.
