I feel at this point I should mention there's a Mystery Science Theater episode that starts out with the mad scientists putting comic books very carefully in plastic bags, when there's a knock at the door. When answered, the guests turn out to be two women, at which point the mad scientist who answered the door runs screaming back to the other one: "AAAAAH! THERE ARE GIRLS HERE!"

I just watched this episode the other day, is why I remember.
