Star Wars parodies were born the minute the movie was declared a hit. This skit is from TheBob Hope All Star Christmas Comedy Special in 1977. Bob Hope is Barf Vader, Olivia Newton-John is Princess Hialeah, and Perry Como is Luke Sleepwalker. Mark Hamill also appears. Hamill said this special was what convinced his grandparents that maybe a show business career wasn't such a bad idea.
