I have only been a fan of The Walking Dead for roughly two years now, mainly watching the TV series and playing the TellTale Games. However, I am now starting to read the original source material, and have read two (going on three) of the Robert Kirkman and Jay Bonansinga paperback books, along with Volume One: Days Gone Bye.
However, I got to thinking about this the other day, and after doing some research, realized that there were some severely bizarre crossovers that I was unaware of. There was apparently a comic called Archie Meets The Punisher and two books based around Batman meeting the Teenage Mutant Ninja Turtles.
With this is mind, I was just curious, have any of The Walking Dead comics ever done crossovers with other non-Walking-Dead-related material?
