It is mentioned during the episode that Buttons has had sex with more than 4,000 women.
Buttons: I don't want to fuck you, Dan, but I will if I have to.
Dan: Face it, Bill. Your entire criminal career has been a litany of screw-ups.
Bill: It's easy to be a Monday morning quarterback, Dan. You try and cover up for an arterial spray!
Dan: Face it, Bill, you were a stupid criminal.
Bill: I was not stupid.
Dan: You had a cab driver wait for you while you murdered a family of four.
Bill: Yeah, you try and flag a cab when you're covered with blood.
Dan: You sent a tape of one your murders into America's Funniest Videos.
Bill: Yeah, if it wasn't for that moonwalking dog, I would have won.
Dan: (hearing about missing pizza delivery boys) This is horrible!
Bill: Yeah, if we don't have pizza boys, where are really stoned people going to get their pizza?
Rocko: Look, it's a skull gumball machine made with a real skull! Great idea, huh?
Buttons: No, it isn't! Who the hell is going to buy that?
Rocko: Lots of people. Kids love real skulls!
