[from trailer]
Billy: What's your stripper's stage name?
Adult bookstore clerk: Do I look like a stripper?
Billy: I'll just call you Cinnamon.
Billy: [to moving truck crew after they helped load his grandmother's corpse into his grandpa's trunk] Thanks for the crime!
[from trailer]
Bicycle man: Don't hurt me! Don't hurt me!
Irving Zisman: Hurt you? I'm 86 years old!
Irving Zisman: My Spanish name is El Mucho Ding-Dong.
Billy: [to the grocery store employee] Sometimes he shits himself.
Irving Zisman: [turns to Billy] I don't shit myself, you little prick!
Billy: [while pushing his drunken grandpa in a shopping cart down the street] You shouldn't drink so much.
Irving Zisman: Pipe down!
[moans]
Irving Zisman: Oh, God...
Billy: [keeps pushing the cart] Do you have any idea how heavy you are?
Irving Zisman: [mumbling] Do you have any idea how I don't give a shit?
Irving Zisman: [to the fast-food worker] We need some chickens and a big side of poontang!
[laughs]
Irving Zisman: I may be too old to stir the gravy but I'm still old enough to lick the spoon, that's for damn sure!
[chuckles]
Irving Zisman: [after putting his dead wife in his trunk] Can we say a prayer? Lord, please look after Billy and I on our journey with Ellie. And Lord, please look after these men because they were very sweet... and also accomplices to probably what was... technically a crime, but... we're not gonna say anything...
James: [walks away] Come on, man! Are you serious?
Irving Zisman: [continues with his prayer] In your name we pray. Amen.
Irving Zisman: [to one of the male black strippers] So I bet you got a pretty big Tootsie Roll, huh?
Irving Zisman: [while making a ham sandwich in the store] Now, let's get some damn mustard.
[first lines]
Billy: [at the law office] You know what I wanna be when I grow up?
Lady: What?
Billy: A fisherman. I want to go fishing everyday 'till I'm rich so I can move right next to the jailhouse so I can be close to my mommy. She got arrested for drugs again, so she has to go back.
Lady: I'm sorry to hear that.
[gives Billy an awkward look]
Irving Zisman: [about his deceased wife] She was a pain in my ass when we were married and she passed away, she's still being a pain in my ass!
Billy: [about his grandma] She passed away.
Woman: [gently] Oh dear, that's very sad.
Irving Zisman: Well, it's not so sad. She was kind of a bitch, but yeah.
Woman: [gasps] Jeez. My goodness!
Irving Zisman: Well, gotta call a spade a spade.
Irving Zisman: [to Billy at the diner] Oh, man. I think all this bacon's getting to Grandpa.
[farts]
Irving Zisman: Sir, can you help me? Can you help me, sir? I don't expect you to understand but I have my penis stuck in the soda machine!
Irving Zisman: You young ladies in the market for a nice bed?
Woman #1: No.
Irving Zisman: Seventy-five dollars.
Woman #2: What's so special about it?
Irving Zisman: It's got that special vibrating feature, you know what I'm saying?
[chuckles]
Irving Zisman: [about a girl Billy knew] Was she your girlfriend?
Billy: Yeah...
Irving Zisman: How long did you go out with her?
Billy: A day.
Irving Zisman: [bursts out laughing] A day? Reminds me of most of my relationships!
Irving Zisman: [to a woman] You know when I was overseas, when you used to sleep with a prostitute, they would squeeze lime juice on your schmeckle to see if you had any diseases. And if you went, "Ooooowww" it means you got something 'cause the cuts burn. I never went "Ooooowww" but one time.
Billy: [after Irving defecates on the restaurant wall] EW, GRANDPA, YOU *SHARTED*!
Irving Zisman: [upon hearing his wife had died] Oh. I thought she'd *never* die!
Billy: [to a random man on the street] You're my dad. High five, Dad!
