Did You Know?
In the Downtown level, outside the Android's Dungeon comic shop, there is a stand clearly displaying two pictures, one on each side. One is the cover of Radioactive Man #1, a Simpsons-related comic book that was actually published by Bongo Comics in late 1993 and was cover-dated November 1952. The other is the cover to Radioactive Man #25, which has not been printed but was featured in the interior pages of Radioactive Man #100, which has been printed. See more
Stop, you idiot!
