Family Matters
Urkel trades Johnny Gill one of his two "gem mint" '52 T Mantles (so that he'll sing to Laura).
You can see the cards from a distance, and I gave them kudos for actually using the Mantle. Given that Jaleel White was a serious collector back then, I wondered if they could've possibly been real. But since it was just the third season and White hadn't been a big star for long, dunno if he would had the $$ to land those during the junk wax era
