This only happens when I see Sam Jackson in a movie. I'm always just waiting for him to get that look in his eyes like you just told him about your date with his mom. I'm always expecting him to freak the fuck out.
This is probably what made the prequel Star Wars movies so intense to me. I was just squirming in my seat thinking how did HE get to be a Jedi?!?!? Don't they know he can't control his anger? Oh, no. Jar Jar is about to talk to him. He's gonna get frustrated and be all like, "Galactic Basic [Galactic_Basic#Basic:_the_common_intergalactic_language] , mother fucker!! Do you speak it?!?"
