The Campout - S2-E5
Audio problem: When Laura and Nellie are on the branch going down the rapids they can be heard talking, but their mouths either don't match with what they are saying or don't move at all.
Audio problem: Jim has been beaten up in front of the Sierra and dragged back into his own car. When they drag him out inside of some warehouse, he says "Take it easy! I'm not struggling, am I?", but James Garner's lips are not moving and the line is obviously dubbed in. (00:24:30)
