Plot hole: Live 50th anniversary episode, aired December 9th 2010 - When Sally is allowed into the rubble to comfort Molly as the firemen attempt to free her, one of them says they'll get Sally a hard hat. When we see her talking to Molly in the rubble, she has no hard hat on and instead one of the firemen is hilariously holding his hand above her head.
Continuity mistake: The bruise on Wilcox's cheek switches from the right side of his face to the left and back again several times throughout the episode.
Continuity mistake: In fake Shemp episode "Commotion on the Ocean" (1956), when the Stooges first greet the large villain on the ship, Moe's hat is flat and he wears an ascot. Instantly the shot changes up close and Moe's hat is poofed up and he's now wearing a necktie instead of the ascot. This was a combination of old footage with Shemp, and a new scene filmed with just Moe and Larry (after Shemp's death). (00:03:00)
