So Is That a Jewish Name, Or...?
Since you're all basking in the glow from last night's bout of crayonic genius, allow me to phone this one in:
This, gentle reader, is an imaginary story (that may not happen, etc.) detailed in Superman's Girlfriend Lois Lane #46, wherein Lois marries a reformed Lex Luthor, resulting in the birth of Larry, who grows up to be known as Black Luthor. Surprisingly, he's not the private dick that's a sex machine to all the chicks, but rather the galaxy's most feared space pirate.
Naturally, the only thing that can reform him, aside from the mind-altering anti-evil ray that the other space pirates get a taste of, is the love of a good woman. And in this case, the part of Good Woman™ will be played by daughter of Superman and Lana Lang, whose plot to ensnare Larry with a kiss full of "evil-removing chemical" lipstick fails rather miserably. Fortunately, they hit it off despite his plan to shoot Earth into the Sun, and as we all know, love conquers space pirates.
But all that is only barely relevant to the fact I'd like to point out about Superman's daughter: Her name--her full name, mind you, as revealed in the story...
...is Joan Superman.
