Superman: The Animated Series (1996)

Mxyzpixilated - S2-E8

Character mistake: In the third instance where Superman manages to get rid of Mxyzptlk, he uses an article full of typos which spell the latter's name backwards as KLTPZYXM. Among the incorrect words is the word "citrimes", in which Superman has included an I and a T, so the correct word in context with the rest of the text should read "crimes" and thus the errors would spell KL-I-TPZYXM. Since there are no vowels in MXYZPTLK, however, what is the additional I doing here - and why didn't Mxyzptlk bother to mark it as a mistake, either?

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.].

In Brightest Day... - S3-E7

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.
