Moe Howard was wearing a hat and smoking a cigarette when Larry Fine and Curly Howard were dumping tin cans onto the rubbish truck and they fall on him instead. In the following shot Moe is not wearing his hat.
When the spring is attached to Curly Howard and Professor Nichols' behinds, you can also see a string inside of it.
As the Professors Nichols and Richmond leave the restaurant, Nichols says he will hail a cab for the both of them. Yet, after meeting Moe Howard, Larry Fine, and Curly Howard a minute or two later, Richmond invites them all into his car, parked right next to the Stooges' rubbish truck. Possibly the result of a deleted scene.
During the dance, Larry Fine loses his shoe. Moe Howard's dancing partner, played by Phyllis Crane, trips on the shoe and falls, striking her head heavily on the floor. This was not scripted, and a gasp can be heard from another cast member before the scene ends abruptly.
The professor does not say he raised the bet to 2 million dollars and then 3 million dollars. They raise the number of people to rehabilitate from 1 man to 2 men and accepted at 3 men. The bet stayed at $50000 all along.
Professor Richmond pokes one of the party guests in the eye and in the next shot, the same guest puts a hand on his cheek indicating that he had been slapped.
