Fearless Fonzarelli: Part 2
Fonzie successfully completes the stunt of jumping his motorcycle over fourteen garbage cans, but in so doing he crashes into Arnold's chicken stand, injuring his leg.
After surgery to repair his injured knee, he begins to fear that the pain will make him feel "uncool". Self-conscious about his condition, Fonzie decides to camp out on the Cunninghams' sofa until Richie decides to use some reverse psychology to literally get "Fearless Fonzarelli" back on his feet again.
