All Kinds of Nasty

I hate flies. They are just really gross, disgusting bugs.

I can handle spiders, lizards, even roaches. But flies do something to me that make me want to rip every last hair off my head.

While I detest flies that are quick and make you look like a complete idiot trying to swat them, I absolutely abhor flies that are fat and big and sort of fly around like they are drunk. It's like, Come on! Fly a little faster, you ugly disgusting piece of nothing!

I have a friend who hates centipedes. He is weirded out by them. What do you hate? What turns your stomach?
