Vacation from Marriage - S2-E6
Other mistake: The camera jostles badly when Lucy steps up on the board to cross the plank.

Revealing mistake: At the Brown Derby, when Lucy bumps into the waiter causing him to trip and spill the tray all over William Holden, we can see that the waiter's hand is taped to the bottom of the tray for the stunt to be done efficiently. (00:15:15)
Lucy Ricardo: How much do you want to bet?
Fred Mertz: Ten dollars.
Ethel Mertz: Well what's the matter with twenty dollars?
Ricky Ricardo: What's the matter with thirty dollars?
Lucy Ricardo: What's the matter with fifty dollars?
Fred Mertz: What was the matter with ten dollars?
Trivia: Lucy, Ricky, Ethel, and Fred all do the impressions of Maurice Chevalier. Thirty-six years later, the same impression is done in the 11th episode of The Simpsons.
