I remember waching Heaven's Lost Property and thinking it was hilarious lol. It was so perverted but funny. It did get kinda real at the end, though. Another hilarious one I watched is one about three girls who form like a game club and are always trying to play games but end up doing so many messed up things lol I can't remember the name but one of the main characters her name is olivia and her armpits are spicy XD
