Heh, I remember the ending after you beat M. Bison. Gorbachaev (sp????) would come and you'd do that russian dance...rofl.
I also remember the time when there was a rumor going on around school that if you beat the game on easy without losing energy once or if you beat the game on hard only losing a round once, you'd unlock M. Bison... lol... you won't believe how hard some people tried.
