I Dream of Jeannie - Season 4 Episode 7

Jeannie's magic makes Tony not only the strongest man (depicted by his easily lifting tables and other furniture), but gets him into trouble at the gym. Tony must compete in a boxing match against a burly Marine, who's the Armed Forces boxing champion. While training, he and Roger discover a series of punches that could fell the champion boxer. But Jeannie inadvertently gets locked in a locker, and can't blink herself out to help Tony, whose strength has returned to normal ... just in time for his boxing match. Of course, Tony's offense is ineffective, and the champion boxer pummels Tony. Finally, after Jeannie is released from the locker (by an unknowing subject using the gym), she manages to use her magic to save Tony from being knocked out (he fells his opponent with one punch!). Alas, both men are down for the count -- the champion from the punch and Tony from his brutal beating, and the match is declared a no-contest.
