Eddie argues to his girlfriend about her modeling when Steve sees Greta nude in Laura's art class, only for Laura to reveal the shocking truth. Meanwhile, Neidermeyer takes Richie and 3J's football and he refuses to give it back. Nick is soon in for a hard lesson in respecting people's property when he is nearly arrested for trying to break in to his own home.

A street gang, known as "The Piranhas", has intimidated Richie and 3J from playing at the local park, and when Urkel tries to intervene, he is quickly roughed up. The street gang begin celebrating their possible new place to deal drugs and play rap music until Bruce Lee Urkel (and similar Richie and 3J variants) show up to even the score. After slipping in the Winslows home, Nick fakes needing a wheelchair and threatens to sue Carl. However, his plans are foiled when Harriette and Eddie exploit and expose his scam and send him on his way.
