There's a line in French Kiss that always pops into my head when people at work (or anywhere, really) are driving me batty. It's one of Meg Ryan's lines, and she's imitating Kevin Kline's character.
"My ass is twitching. You people make my ass twitch."
Somehow it always makes me feel a little better to mutter that under my breath as soon as I'm out of earshot. Anyway, just thought I'd put that out there.
