- Mikey: You know, everybody gives me a problem about the grinder being face up and they think my middle name is "safety". But it's not... It's "danger". No, I'm kidding... It's "Joseph".
- [after watching his beloved Nissan being trashed by the guys]
- Mikey: That car has lasted nine years... longer than any relationship with a girl I ever had.
- Keith Quill: I've got question for you guys, just so I know... How many people does it take to run one machine?
- [a welder hits the frame of the Comanche bike with a hammer]
- Vince DiMartino: I can not emphasize how much you can not do that!

- Paul Sr.: It's not just an Orange County Chopper, it's a New York City Chopper.
- [Paul Sr. gives Cody the Old School chopper]

- Will Smith: [after test driving one of the custom bikes] I've GOT to get me one of these!
- [after seeing Rick has cut his hand on the drill press]
- Paul Jr.: Somebody needs to get him to the hospital!
- Paul Sr.: [yelling at Paulie] You're the biggest slob I know! Stop everything and get this place cleaned up!

- Mikey: [on the radio to Campo to get the trailer keys] Campo... We're Pissed... You Key-Hordin' Pixie!
- Paul Sr.: [berating Paul Jr] You are the most inconsistent, unreliable person in this entire fucking shop and if you were to make an example to the rest of the guys out there, they would all end up just like you, but I don't let that happen, I don't let that happen.
- Paul Sr.: [scolding Paul Jr. for the disheveled condition of the shop] You know what? I'm done talking with you because you are the biggest slob I ever met in the world. So why am I even debating this with you?
- Paul Jr.: There's certain things you can't do anything about.
- Paul Sr.: Yes, I can, because I own the place.
- Mikey: [in the UK, Sr. is riding the clutch trying to drive on the opposite side of the road and drawing attention] From London!
