"Jeopardy!" – Alex Trebek's comment that Marge owed the show $5,200 (based on her negative $5,200 score, which cannot happen in real life on the show) is a spoof of criticism concerning Trebek's sometimes stern rules enforcement of shows he hosted, particularly during the early years of "Jeopardy!"

At the time of the episode's airing and since then, Alex Trebek shaved off his mustache for a clean-shaven look.
