Stefan Urquelle is the alter ego of Steve Urkel from the family sitcom Family Matters. Stefan is an arrogant ladies man that is the polar opposite of Steve. He debuted in the 1993 episode “Dr. Urkel and Mr. Cool”, after Steve drinks a potion called “Cool Juice” that he hopes will win Laura’s heart.
Cool Juice? Stefan Urquelle? Family Matters doesn’t get enough credit for it’s creativity. This is one of Urkel’s best characters. Props to Jaleel White too.
