What's your favorite lines from tv shows?

I've got a few. I just saw a rerun of one of my favorites.



From Criminal Minds, Prentiss is taking about her cat, Sergio, whom she passed off as her new boyfriend, when talking to her therapist. She says to Hotch, "He is the perfect man. He doesn't hog the covers, and he poops in a box."



There are too many from Firefly for me to just them all.



So what are your favorite lines?
