Can you believe that the Teenage Mutant Ninja Turtles first hit the comic book page a mere 25 years ago this year? I partook in the shell-ebration by soliciting these karaoke-themed sketches from artists Jim Lawson and Steve Lavigne at Comic Con! Also, I couldn't avoid the evil Shredder's attack . . .! He wanted my lunch money, but dollars are worthless in Dimension X.
