Dennis: (referring to his memoir) Charlie, what the hell were you doing with it? Dee: Well, uh, since he can't read, I'm guessing he was masturbating to your pictures.

Charlie: You know what, what are you doing to me? Why are you doing this? You've been riding me, now your accusing me of things, and you just don't get it. You don't know why I do the things that I do. It's nuts! You don't know how hard I got it, Dee

Frank: This is some sweet smut! I'm all boned up over here!

Charlie: In case you have to pee pee, I got this for ya. Dee: No wonder it reeks in here Charlie, you have open cans of pee everywhere!!!

Charlie: Eat one of these, you're gonna wanna huff a little glue and drink some beer... Dee: This is cat food, Charlie...

Charlie: I have fifty cats howling outside my window because I have ten thousand rats running around my building! Dee: Stop yelling, you're spitting cat food at me... Charlie: I'm not an idiot, there's a reason to do the things that I do...

Frank: (while peeing into a tin can) Ocupado...

Charlie: Wake up! Let's go... Time to start the day, time to get up!!!
