Other mistake: When Ricky puts the baby in the crib and begins telling him the bedtime story, in the closeups Little Ricky's sitting up beside the crib rails (at Ricky's side of the room), but in all the wideshots when the camera pulls back to show Ricky's lively storytelling, we can see that Little Ricky is not where he should be.

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)
Lucy Ricardo: How much do you want to bet?

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.





Answer: There is no reason. It's a just a silly plot device, typical of the era. Women characters were often portrayed as making uninformed assumptions or decisions.
