During the scene when Al is on his knees looking under Bud's bed, the shadow of a crew member can be seen moving over Al.
Jefferson: (referring to Bud) So, where's the cool guy who's ready to leave home and bag some babes?
Al: Right here!
Marcy: Please. You can't even bag your own wife.
Al: Oh, I can bag her, but it doesn't do me any good, I remember what she looks like.
Peggy: Mom does not eat between meals.
Al: Oh, no, Peg, because in order to eat between meals, the first meal has to end.
Marcy: I do remember my first apartment. My roommate and I were both single, both bursting with ripe, flowering womanhood. The sexual revolution was in full swing and we were a-happening.
Peggy: Wow. I'll bet you were having sex all the time.
Marcy: No, that cheap slut of a roommate stole all my boyfriends. I've never forgiven Mom for that.
Peggy: I've always wanted some place where I could stretch out and do nothing.
Al: Well get in the car, I'll take you to the morgue.
Peggy: (after getting off the phone)That was Dad. He and Mom had this big fight, and now Mom left and he can't find her.
Al: Did he look behind the Rockies?
Al: Who the hell would put a bear-trap in an outhouse?
Ephraim Wanker: They wouldn't. That ain't no bear-trap, that's a human-trap.
Al: Well, why would you want to trap a human?
Ephraim Wanker: I don't know, ask the bears, them was the ones who put it in there.
Al: Don't you know that all horrible things happen in threes: Celebrity deaths, Pauly Shore movies, Wilson-Phillips. In my own case: Marrying Peg, Bud not moving out, and 3-2-1...
Peg: Al, something horrible has happend!
Al: The hell you say!?
