You should check out the one in the library. What they do is they all get a card (6 people at a table) and one of them gets a big X on the card. This means they have to do the following thing and make as little noise as possible to stay in. Last person had to eat a huge roll of wasabi...nasty, but funny. Another guy had to be bitchslapped by this fake arm thing, lol.
Also the one where they go to people sleeping. One they carried onto a horse track and tie his legs to the horses leg, then they fired in the air and the horse ran like crazy with the guy dragged in the mud. Another they pushed off a giant water slide on his mattress, lol.
Then there's the weirdest one. 6 guys (same ones always I think) sitting in a classroom watching a TV. The TV shows a Japanese guy trying to speak English but he messes up completely. These 6 guys are not allowed to laugh and when they do, they are sent out. BUT BEFORE THEY ARE SENT OUT, THEY ARE SLAPPED REAAAAALLY HARD with a giant stick on the ass. LOL, weird stuff but funny!
