Superman immediately decides that the best way to deal with the situation is to murder the Super-Imp at his earliest opportunity, even though he suspects it's actually alive. Fortunately--if you're Superman, anyway--the incredibly creepy Fun Size Superman sacrifices itself to save him from a basketball-sized chunk of kryptonite launched from a catapult by some local gangsters. So pretty much just another Tuesday in Metropolis.
Kate Bosworth's Lois Lane from Superman Returns has become the mother of a little boy in the time Superman's been gone, but back in the comics of 1965, Lois's interest in children veered into slightly less maternal territory.
In one of her many--yes, many--attempts to use the science of time travel to score with Superman, Lois hops into the time bubble for a jaunt back to pre-explosion Krypton for the allegedly humane purpose of keeping it from exploding (Surprise! It doesn't work!).
Once that's done, however, she immediately sets her sights on luring hunky scientist and Superman's future father Jor-El away from his girlfriend, but after getting smacked around and called a hussy by Superman's future Mom, Lois gets the idea that maybe the Kryptonian singles scene isn't quite right for her, and heads back to the future...
