Audio problem: When Cyril is driving up the bus up the mountainside, and Don is talking to him over his shoulder about Barbara, Cyril is heard to say "Don, Bachelor boy". However this is not what the original line was, as it can be seen that he is speaking different words. The line was probably changed between filiming and recording the over dubs.
Audio problem: At the end of "Stranger in Town" after Don falls into the lake, he says "Oh women!", but his mouth doesn't move.
