For Tiny, he would hate if you mention the Holocaust. As for Devon, what annoys me the most is something I finally realized today: his "milk" isn't funny. He doesn't overreact, he doesn't say stupid shit that you can chuckle or maybe even say "what a tard!". He says retarded crap but it makes you look at him with how much pilpul he's pulling out of his ass, wondering how low can he sink.
Tiny, however, does something funny, which is why we laugh. Same with Balldo/Crackets, with his retarded lifestyle.
