In A Piece of the Action, Kirk invents a card game known as Fizzbin that he uses to catch the interest of their guards so they can catch them off-guard and subue them:
In 1950, a similar gag was used in The George Burns and Gracie Allen Show. Burns invents a game named kleebob to confuse his wife (you can skip the first 74 seconds or so of this clip):
While the rules for fizzbin and kleebob are quite different, the gag or idea is the same: Invent a card game that will confuse someone else so you can trick them.
After posting this question on a sister SE site, asking if there is a source for the kleebob gag, it also makes me wonder if the kleebob scene was the source or inspiration for the fizzbin scene in Star Trek.
Is there any evidence that David Harmon or Gene Coon were familiar with this scene or if this is their inspiration for fizzbin?
