Don't Get Mad, Get Even - S2-E21
Plot hole: In the bath house at the beginning, Heyes and Curry, who should be using their aliases, call each other by their real names several times while the proprietor, who's a stranger to them, is preparing hot water nearby. The man must not be up on "the two most successful outlaws in the history of the west," though: he doesn't race off to turn them in and collect the reward. (00:04:40)
Don't Get Mad, Get Even - S2-E21
Factual error: A grumpy Heyes tells Georgette and Curry that he's been sleeping in a stable loft for two days without a bath or a shave. But he's completely clean-shaven: not even a hint of stubble showing. (00:15:00)
Suggested correction: He is not "completely clean-shaven." He has evident facial hair.
