1 visible crew/equipment mistake in Be A Pal
Starring: Lucille Ball, Desi Arnaz, Vivian Vance, William Frawley

The Séance - S1-E7
Continuity mistake: After Lucy tells Mr. Merriweather that he's invited to the seance, when it cuts to Lucy unfolding the card table legs, note the couch behind her with one normal seat cushion on the left, but in the next wideshot there's an additional shorter cushion under the normal cushion. The small towel also repositions itself neatly on the couch. (00:11:55)
Ethel Mertz: Rome wasn't built in a day.
Fred Mertz: Well, Rome wasn't built like you either.
Trivia: Fred and Ethel's bickering relationship didn't require much acting; in real life Vivian Vance and William Frawley didn't care for each other at all.
