This marks the first appearance of Walter and Kelly Gaines.
Streaming video places this episode out of sequence, accidentally appearing after "I Kid You Not" which is when Woody borrows Sam's car to take Kelly on a date.
The expression "the proof is in the pudding," a shorter version of earlier "the proof of the pudding is in the eating," has been used in that form since at least 1860.
Few viewers were aware of it at the time but they had previously seen Jackie Swanson ((Kelly) in a key role in a blockbuster motion picture. She played the drugged jumper Amanda Hunsaker at the beginning of Lethal Weapon (1987).
Two nights after this episode aired Ted Danson hosted Saturday Night Live, making him the second cast member to do so.
