Steven Urkel's very cool alter ego. After years of being the world's most renowned nerd, Steven Urkel finally used his scientific prowess to create something useful. Steven Urkel created a machine which could transform him into a cool ass guy who actually got laid. Within a few episodes he started macking his ugly neighbor Laura, who he had been chasing for years. That self righteous superficial bitch finally fell for him and he began hittin' it steady. His invention however could not change or mask his voice. Even after transforming from Steven Urkel to Stephan Urkelle, he still sounded like he had a hot wheel in each nostril.
Steven Urkel: "Did I do that?"
Stephan Urkelle: "Yeah I did it, and you love it."
