Why TMNT Mutant Mayhem Almost Removed Viral "Ninja" Reference: "That Is The Dumbest Thing"

Teenage Mutant Ninja Turtles: Mutant Mayhem‘s bizarre viral ninja reference has been explained. A scene from the newly released animated movie features a training montage that ends with the turtles showing off their moves while the phrase “I’m a ninja” blares on the soundtrack. The phrase is taken from a viral music video from David Seeger and Holly Whitstock Seeger titled “The Karate Rap,” which was originally filmed in 1986 but didn’t see the light of day until 2012. The humorously cheesy song features the line “I train in my car, I’m a ninja,” which was sampled for the movie.
