I loved these books. I was thinking of doing a post on this stuff myself. The archie turtles universe was so much fun, and I miss it. One of my favorite books as a kid was a read-along with the Leatherhead, Intergalactic Wrestling, and Wingnut issues done in cheesy radiodrama fashion.
Recently tracked down the Furrlough issues with the Murph/Allen Ninjara snippets in 'em. They're really not at all what I was expecting. Maybe I'll post a bit of 'em soon.
