Ranma ½ (1989)

Season 1: Episode 155

Ranma's got the basic moves down, sure, and that uniform really is cute, but then it turns out that it's Kuno's kendo match he has to cheer for. No way! Worse, Mariko's crush on the so-called 'Blue Thunder' means the only way Ranma can win-and avenge Akane's honor-is to somehow best Mariko in a cheerleading contest. Under these circumstances, how cheerful can Ranma be expected to be?!
