The Teenage Mutant Ninja Turtles. Most kids today have no idea that the Teenage Mutant Ninja Turtles are not a new idea. They might watch the current cartoon series and think that it was the very first time the animated Teenage Mutant Ninja Turtles were on television. They might even watch the new trailers for the highly-anticipated movie being released this summer and not even realize that there was an entire trilogy of TMNT movies created back in the 90s. The Fine Brothers tried to use their “Kids React” series to bridge the gaps between the generations by introducing the original Teenage Mutant Ninja Turtles cartoon to them. Listening to their reactions will make you feel young again – especially when you start to see them dancing to the theme song. Another interesting fact that you will learn by paying close attention to this Kids React video is that Chuck Lorre (the creative genius behind such hit TV series as Big Bang Theory and Two and a Half Men) composed the theme song of the original Teenage Mutant Ninja Turtles cartoon and even produced the series. Small world, isn’t it?
