The Fresh Prince of Bel-Air episode Love at First Fight
February 18, 1991
The twenty-first episode of The Fresh Prince of Bel-Air is about Will trying to impress Kayla, one of Vivian's students, and in a scene when she askes Will if he had ever memorized too many things at once that his head was going to bust, he responded, "No, but I once got up to the third level of Super Mario Bros. and yo it was hectic up there!".
The Fresh Prince of Bel-Air's company Warner Bros. had no right over Nintendo's Mario, but they only included a minor reference to the series.
