Factual error: In the hotel bar just after his lecture, Frank and his buddy are talking. Frank says that his wife "set the clock forward" (and thus he was late for the lecture on efficiency). His buddy asks: "she actually set the clock forward?" Ryan responds "she set it forward." Thus, he should have been early, and not late for his lecture. She should have set the clocks backwards to make him late.

Ed: What is?
Frank Allen: Keeping the groom away from back exits.
