Heavy Metal - S2-E23
Continuity mistake: Season 2 episode 23 "Heavy Metal": In the beginning, when Metallo and the Intergang goons raid the bank, the goons use conventional submachine guns. When they start tearing through Irons' neighborhood looking for Superman, the goons use the same guns, which have, however, suddenly become laser blasters.
Mxyzptlk: Your three months are up! And this time you're not gonna cheat me of my fun.
Superman: Oh, it's you again, Mr. Kltpzyxm.
Mxyzptlk: NOT Kltpzyxm! Mxyzptlk! Now,  the first thing I'm gonna do - ah, nuts! [Disappears.].
Trivia: When Kyle is knocked into the airfield by Siniestro, he crashes into a Sabre jet. As he recovers, we read the pilot's name as Col. Hal Jordan. This is the name of the second, Silver Age Green Lantern.
