Frankie Melina (Darrell Fetty) is a scary and tough gang leader. His gang, The Dukes are feared around town and Richie and his friends normally have the good sense to keep away from them but Richie inadvertently runs right across their paths when he assists Frankie's younger sister who is being bullied, and escorts her home safely.
Needless to say, Frankie is very grateful for this and is very nice to Richie, well, as nice as a gang leader can be anyway! However, Frankie is not so nice when Richie 'trespasses' on Duke turf in order to claim back Potsie's pushbike which has been stolen by the gang. It could be a tough situation and it looks like the boys will need help getting out of THIS pickle.
A very funny episode, lots of laughs and some excellent acting by both Anson Williams and Ron Howard.
