Barn Burner - S1-E11
Continuity mistake: When Earl is in the Crab Shack discussing the punishing of the children, there is an empty tray on the counter in front of Crab Man, but when the shot changes, Crab Man is holding the tray with a bottle of beer on it. The shot changes back to Crab Man holding the empty tray, then changes back to him holding the tray with the bottle on it. (00:01:50)
