Superman vol.1 No.51 - Cover Date Mar-Apr 1948
Superman once again finds himself obligated to provide his services to a crook, and deliberately flubs every request so as to honor only the letter if not the spirit of the contract. This plotline only debuted within the last few months, but has already become the most-often-trod premise in any of the Superman books. Suffice it to say, if you ask Superman for “the world’s biggest diamond,” he’s going to carve you a baseball field, just be aware of that.
Canny villains with access to a supremely powerful magnet commit a series of daring airborne raids which are first blamed on the Man of Steel himself, and even prove that their powerful magnets can deter Superman! He uses magnets against magnets to fill in the gaps where his super-powers have failed him, but even this exciting conflict doesn’t hold a candle to the book’s chief adventure, “Mr.Mxyztplk Seeks A Wife,” wherein to avoid marrying the unappealing daughter of his King, Mxy tries to trick Lois Lane into becoming his bride. He almost succeeds, too, betting on his annoying personality to overwhelm everyone’s reasonable objections to the ceremony.
All that keeps Lois from having to append her professional name to Lane-Mxyztplk is Superman taking advantage of the high pressure of the ceremony itself to trick the imp into speaking his name backwards and disappearing to his home (where, hopefully, he’ll be promptly married off to the princess, and won’t return to force Lois to make good on her hurried promise).
