I linked a week ago to Again With the Comics' post on the Helmet of Hate story in Jimmy Olsen. As you will recall from reading that post, at the end of the story it was revealed that the entire plot was based on Plan "J", a pre-arranged scheme where Jimmy Olsen was to do certain things to help out Superman.
As it happens, I was re-reading Lois Lane #29 today, and the cover story in that issue reveals Plan "L":
It's a ridiculously convoluted plot, obviously partly so to provide us with that entertaining cover scenario. Here's Lois explaining what Plan "L" told her:
Okay, but what if he's in trouble from Green K near Niagara Falls, or in Egypt? Was there a plan for that? At any rate, Lois sets about kissing every superhero she can get her lips on, which on this day in Metropolis just happens to be Green Arrow, Aquaman and Batman. After they're covered with her lipstick, they wipe it off onto a hankie which Batman flies up to the Fortress. Superman then coats his own face with the lipstick, because it has a form of Red Kryptonite on it that provides temporary immunity to Green Kryptonite. Oh, and she had to do it in that zany fashion because the villains were spying on her:
Note to self: When planning to keep tabs on Lois Lane, make the crystal eye a little less obvious.
Plan "P", for Perry White appeared in Action #295, discussed in detail at the Silver Age Sage.
