Charlie: I think you should do it!
Charlie: Look, an opportunity like this only comes around once in a lifetime right?
Charlie: And so you'd be a fool to let it slip through your fingers.
Mac: Yeah! That's what I'm thinking! But... it's Dennis' and Dee's Mom...
Charlie: Well that means that no one ever ever is going to find out.
Mac: That doesn't make any sense...
Charlie: It doesn't have to make sense!
Mac: You're right! I'm gonna do it!
I'm going to stab him. I'm going to stab his face off!Waitress

Charlie: Yeah... that's a terrible thing... a terrible thing for you to see that.
