Gallagher Melon Crazy on VHS video. TV short starring Gallagher, Bill Kirchenbauer. Directed by Joe Hostettler. 1984.
From the VHS box cover:
It’s official. Gallagher, America’s most outrageous comic has gone Melon Crazy!
The first warning sign of Melon Craziness is a tendency to collect strange “melonabilia” like huge thirty foot watermelons, watermelon blimps, or three-piece watermelon suits. (And other very strange piece of melon matter.)
The second warning sign is a tendency to hang around with other crazy people like special guest comic Bill Kirchenbauer (Tony Roletti of Fernwood Tonight) who does impressions of xerox machines. And the third sign of melon craziness is the messiest Sledge-O-Matic demonstration of all time. Take home your copy today… and stand back! SPLAT!
