Al Jaffee's fold-ins for Mad magazine were maybe the best part of the magazine. I always enjoyed getting to the end of my weekly Mad magazine just to see what perverted fold ins might await. I always tried to figure them out, did a pretty good job with some of them but whiffed badly on most. Guys, for your enjoyment, here are the fold ins from the 1960s to the present, in interactive form. Enjoy the ride back to your childhood. You are so welcome!
