“- Saul Silver: How about in the park, when I said you were my friend... you didn't say anything back.
- Dale Denton: Well, that's easy. It's because we're not friends. You are my drug dealer. The only reason I know you is because I like the drugs you sell. If you didn't sell drugs, I would have no idea who you are, and I wouldn't be here right now.”
James Franco - Saul Silver
Seth Rogen - Dale Denton

“- Valerie: A ufo landed in my pool and they captured me but we made friends and I fed them pop-tarts and, um, they're here now, but Ted's coming home tonight so you've got to cut their hair.
- Owner of Beauty Shop: What did you say?
- Valerie: Oh, nothing. I'm on drugs.”
Geena Davis - Valerie

“A friend with weed is a friend indeed, but a friend with gold is the best I'm told.”
Warwick Davis - Leprechaun

- Coroner: I'm very sorry, Inspector. But I can't make another autopsy. Because the body was cremated yesterday.”
Alan Hale - Inspector Mason
John Dilson - Coroner
