Marilu Henner, Hugh Fink - S8.E192

Mailbag: "How long has Paul been bald?" Dave fears that this might be a sensitive question, but Paul rubs his chin anyway. A flashback reveals that Paul used to have a long, wavy mane before an accident with Dave's chemistry set turned him into a bald, hideous freak. Vowing revenge, Paul turns into a superhero and eggs Dave's car.
