When Tyler, Cornelius, and his wife are in court with the orangutans, and after Tyler gives Cornelius the note to read to the judge, Cornelius gets up from his seat and lets one loose! (passes gas, cuts the cheese) It's so funny!
The overall scene is very serious, since Tyler could be screwed. A flatulence added to the midst of the discussion is totally inappropriate, and adds nothing to the story...except a few laughs. I guess it COULD have been on purpose, but why?
