Okay was lookin around and YAY i found them rather than type myself i am just going to copy and paste from wikipedia:
A single episode titled "Buffalo Gals" was banned due to its content. Because of the innuendo implying that the Buffalo Gals are lesbians (the carpet calling card Cow uses to find The Buffalo Gals, Mom's line "It's the Buffalo Gals, a biker group that randomly breaks into people's houses and chews on their carpet," the name of one of the bikers is "Munch Kelly", the Buffalo Gals play softball and talk about "pitching" and "catching"), Cartoon Network only aired "Buffalo Gals" once, and since then it was replaced with "Orthodontic Police".
i couldn't find the full episode of this but will show you the sample of it
seriously i lold my ass off XD
and this one was banned because the red guy was called the devil and lured chicken into hell with cigaretes because chicken smoked (yeah dumb reason)
