There has never been a better time than now to make a T-shirt for our viral video! The Karate Rap finally made it to the big screen in the new Teenage Mutant Ninja Turtles movie, Mutant Mayhem. Listen for Sensei Dave’s infamous “I’m a Ninjaaaaaa……” heard twice in the show. The 100% cotton men's classic tee will help you land a more structured look. It sits nicely, maintains sharp lines around the edges, and goes perfectly with layered streetwear outfits. Plus, it's extra trendy now! 

Share our video with your friends—a QR code to YouTube is on the left sleeve. Karate! Train your body!
