Continuity mistake: The interior shots of the airliner to Vegas depict a wide-body, two-aisle airliner. However, the aircraft shown during take-off is a Boeing 757, a narrow-body, single-aisle airliner.
Suggested correction: It actually shows a UAL 767 or 777, either of which are twin-aisle aircraft.
Other mistake: The wedding is officiated in Illinois but the cop car is from Wisconsin.
Revealing mistake: Despite her claiming to be topless you can see what looks like a tube top on Kristen Wiig during her attempts to get the state cop to notice her.
Suggested correction: No, she's not wearing a tube-top. Looked up the scene on online. She has her hands covering her nipples, and her passenger Helen has her arm up in a gesturing manner partially covering her breasts, but there's absolutely no tube-top in sight. (I think you may be seeing part of Helen or Wiig's arm and think it's part of a tube-top).
