When Will is talking to the couple at the chapel he says "So you're having a baby. What a wonderful way to say I love you." He's paraphrasing the lyrics to Paul Anka's 1974 hit "(You're) Having My Baby."
Alfonso Ribiero and Lark Voorhies would become an onscreen couple once again on the LL Cool J sitcom "In The House" shortly after Ribiero joined the show when Fresh Prince ended it's original run on NBC.
This episode aired a few months before Saved by the Bell (1989), a program that had Lark Voorhies as a principle cast member, ended its run.
