Dragon Ball Z - episode 89 - 07 May, 1991

To prove that he's the strongest of all, Frieza uses only his feet and not his hands to fight Goku. While it seems that Frieza has the advantage, Goku manages to land some solid blows, making the tyrant break his word and use his hands. Meanwhile, Bulma finds a frog, unaware that it's Captain Ginyu, as he prepares to switch bodies with her. (Source: Wikipedia)
