This reminded me of those little Christian comic books about going to hell that get left around for heathens to read. Except, they are usually better done.
I know the ones you are talking about, they have been around for many years.
When I was a kid, I would blank out the words in the bubbles and give the characters a new dialogue.
I found sitting on top of a urinal in a truckstop near Kilgore, Texas a couple of months ago. It was titled, "Party Girl," and was about a girl that went down to Mardi Gras and is saved from the sin and depravity there by her grandmother.
