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, Larry, and Curly 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 loses his shoe. Moe'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.
