Scene from Bachelor Party, going from memory but it's been ages since I've seen it...
Indian pimp: "Can only have girls for an hour. Longer than an hour and Milt will be coming."
Gary: "Who is Milt?"
Indian pimp: "This being Milt."
Milt is about 7'2'', takes off his hat, and then breaks a window with his head.
Indian Pimp:"Pretty heavy, hey dude?"
Indian Pimp: "Girls back in one hour or Milt cuts your balls off, now shake."
Gary and Indian pimp shake hands, Gary walks away.
Gary:" I just bet my balls...and shook on it."
