The movie "Jay and Silent Bob Strike Back" has a ton of inside jokes:
Tricia Jones: [on "Bluntman and Chronic: The Movie"] Well! That was just another paean to male adolescence and it's refusal to grow up.
Alyssa Jones: Yeah, sis. But it was better than "Mallrats". At least Holden had the good sense to leave his name off of it.
Tricia Jones: Why didn't Miramax option his other comic instead. You know, the one about you and him and your "relationship"?
Alyssa Jones: Oh, "Chasing Amy"? That would never work as a movie.
[Cock-Knocker (played by Mark Hamill) has gotten his hand chopped off]
Cock-Knocker: Not again.
Jay: Hey, wait a second! Aren't you the guy who fucked the pie!
Jason Biggs: You see! It's never "Hey! You're that guy from Loser" or "Hey you rocked in Boys and Girls." No, it always comes back to that fucking pie! I'm HAUNTED by it!
James Van Der Beek: You put your dick in a pie!
Jay: Miramax? I thought they only did classy pictures, like "The Piano" and "The Crying Game".
Brodie: Yeah, but then they made "She's All That" and it went downhill from there.
Matt Damon: Just take it from "It's a good course."
Ben Affleck: Oh, now you're the director.
Matt Damon: Hey shove it, Bounce-boy. Let's remember who talked who into doing this shit in the first place. Talking me into Dogma was one thing, but this...
Ben Affleck: Hey look, I'm sorry I dragged you away from whatever-gay-serial-killers-who-ride-horses-and-like-to-play-golf-touchy-feely-picture you're supposed to be doing this week.
Matt Damon: I take it you haven't seen Forces of Nature?
Ben Affleck: You're like a child. What've I been telling you? You gotta do the safe picture. Then you can do the art picture. But then sometimes you gotta do the payback picture because your friend says you owe him.
[They both take a beat and look at the camera]
Ben Affleck: And sometimes, you have to go back to the well.
Matt Damon: And sometimes, you do Reindeer Games.
Ben Affleck: See, that's just mean.
