This episode was filmed early in the season. You can tell Sam has his earlier hairstyle from the original pilot. Also, in an earlier episode, someone wrote "the Double Deuce" on the chalkboard in the back pool room. This is a reference to Buzz Crowder's 22nd infantry brigade squad in World War 1.
Aired the same night as Rhea Perlman's (Carla) last appearance as Zena Sherman on Taxi.
Buzz mistakes Norm for his old buddy, Pinky Peterson. Norm's last name is Peterson, but he doesn't comment on this.
A fake license plate can be seen above the piano that reads "TAX-A-CHUSETTS." This refers to the high income tax Massachusetts claimed to have had in the early 1980's compared to other states.
