During the early seasons of Family Matters, Laura worked at a hamburger joint called Leroy's (which was burned down by none other than Steve Urkel--then after Leroy retired to Florida it became Rachel's Place). In the Perfect Strangers episode in which Larry's sister Elaine announces she's going to New York ("The Big Tomato!" according to Balki) in lieu of college, later that night they're all at a jazz joint (where Elaine plays the piano so beautifully that she would be the envy of many a concert pianist), and the blue neon sign outside said that it was Leroy's.

Just another connection between Family Matters and Perfect Strangers!!!
