This really doesn't belong here, but there isn't a thread titled "Things that make you want to murder the person who is doing them," so, here goes:
People who approach you at parties, ask the usual bullshit questions, then make snide/snooty comments about your job and/or your school.
That's right, Mr. Rich Fuckwit. I have a shitty job, and I went to a shitty school. It's because I'm fucking poor. Like so goddamn poor that if you were as poor as I am for five seconds you would commit suicide in despair at the shock of it.
Guess what, though? All that money can't make you as smart or as polite as me. The proof is that I didn't kill you (polite) so I wouldn't go to jail. (smart)
Jesus Christ. I cannot believe people do this shit. It's like they've never seen a movie and are as such unaware that everyone fucking hates their character. Or worse, they're aware of it, but they don't care.
EDIT: also, this is my favorite thing ever:
"I AM A SELF MADE MAN AND I HAVE NO PITY FOR THOSE WHO ARE POOR BECAUSE IF I WAS ABLE TO GET RICH BY BEING A COMPLETE DICKHEAD EVERYONE ELSE SHOULD ALSO BE ABLE TO GET RICH BY BEING A COMPLETE DICKHEAD"
