A white sheet disappears and reappears on the floor during the pie fight scene with Moe, Larry, and Mr. Allen.
When Larry accidentally hits Moe in the back of the head with a pie, he almost bursts into laughter.
When Larry washes his hands, he goofs up his line "What do you think I am. anyhow?"
Mr. Norfleet gives his address as 1414 Bleecker Street. However the number on his house clearly reads 1727.
When Mr. Norfleet informs the boys that his painting was stolen, Larry remarks to Moe that Shemp loves pictures. This would imply that Shemp may be a suspect in the theft of the painting, but this supposed character trait is never mentioned or demonstrated - not before and not after - and Shemp is never even confronted following Larry's now pointless comment.
The re-dubbed line by Emil Sitka, "Change your clothes, dear. You're all wet." is to make up for the inserted shot of the actress getting hit with a pie, lifted from stock footage from Half-Wits Holiday (1947) and none of the party guests in the new footage appear in the stock footage.
