Mr. Mxyzptlk: We're gonna many merry games, you and I.
Superman: A game has rules. Your stunts are just random idiocy.
Mr. Mxyzptlk: Okay, I'll give you a rule: you make me say, spell or otherwise reveal my name backwards and I'll split until our dimensions come into alignment again, in about, oh, three months.
Superman: I can't even say your name forwards, how am I supposed to say it backward.
Mr. Mxyzptlk: No, dope! You don't have to say it backward. You have to get me to say it!
Superman: Say what?
Mr. Mxyzptlk: KLTPZYXM!!!! Gosh, you're thick! Now for the last time-- (realizes what happened) Ah, nuts! (disappears)
Mr. Mxyzptlk: Your three months are up. And this time you're not gonna cheat me out of my fun!
Superman: Oh, it's you again, Mr. kltpzyxm.
Mr. Mxyzptlk: Not kltpzyxm! Mxyzptlk!! Now the first thing I'm gonna do-- (realizes what happened) Ah, nuts! (disappears)
Gspltsnz: Oh, Mxy, I don't like the way you're obsessing over this Superman person. Using our powers to torment humans is so... three dimensional.
