Mxyzptlk uses a magic tape recorder to reverse/pause/fast forward the superfriends' actions making them constantly fail.
Then the whole superteam keep chanting his name "Mxyzptlk, Mxyzptlk, Mxyzptlk" and he finally replies "yes Mxyzptlk is my name and you'll never get me to say it backwards" and then that monkey sidekick of the wondertwins plays what he just said in reverse (specifically his name) and he is defeated.
