Baseball broadcaster Harry Caray welcomes astrophysicist Dr. Kent Wahler to his astronomy program, then derails the interview almost immediately. Wahler tries to discuss the possibility of life on Jupiter's moons, but Harry wants to rank planets, recount his dangerous experiments with staring at the sun, and imagine a moon made of barbecue. The guest grows increasingly bewildered as Harry wanders into a discussion of mad cow disease and offers conflicting explanations for his nickname. Harry ends by announcing Albert Einstein as next week's guest; even a whispered reminder from Pete that Einstein is long dead does little to discourage him.
