Say My Name
I watched some episodes of the first season of Supergirl on CBS, mostly because of lead Melissa Benoist. I haven't been watching since it moved this season to CW, but I just noticed that last night's episode feature Mister Mxyzptlk. I wish I'd watched (even though he now seems to be a dashing young man rather than a cigar-smoking pixie) just to hear how they pronounce his name.
He was a mischievous imp who'd come to our dimension just so he could mess with Superman. And the only way to get rid of him (for only 90 days) was to get him to say his name backwards. Even as a kid, this cracked me up. Here's a trickster, having fun at Supe's expense, and literally the only thing he has to worry about is not saying his own name backwards, which is hard enough to do even if you want to. Yet somehow, someone always figured out a way to get him to do it.
I'm sure Supergirl figured out some way. Or did they change the character so much there's some other way to deal with him?
