Dragon Ball Z - episode 73 - 15 Jan, 1991

Ginyu tries to power up with Goku's body, but it turns out that Goku's right, Ginyu can't reach Goku's body's full potential, because he doesn't know how to unite body and mind. But even at a relatively low power, he can still overpower both Krillin and Gohan. Vegeta arrives, and begins to fight Jeice. Having recovered from severe injury, Vegeta has greatly increased his power, and easily overpowers and kills Jeice. (Source: Wikipedia)
