That character is stupid because even they don't look very bright compared to the stupidest 1% of the human population. I don't watch real life tv shows/movies a lot, but from what I've seen western tv(mostly america) shows is better consistently. I don't think I've ever seen a western cartoon or real life tv/show/move/etc where there is a supposedly normal person who has a suddenly lapsed of Immediate Total Retard Syndrome. edit: also I noticed more guys are usually idiots vs girls. But maybe i'm just biased because i'm a guy.
