Teenage Mutant Ninja Turltes, oh yeah. A cult PHENOMENON in the late 80's that lasts, till pretty much now I'll be honest. It started as an underground comic, had a mini series cartoon that grew into one of the most popular cartoons at the time, a second comic that was tied in with this show, three live action movies, a CGI movie later along with another cartoon series and MERCHANDIZING!! Cream pies, action figures, cereals, tapes, music CD's, blankets, Batman Toys, … more
I watched this show all the time when I was an adult and watching two boys around 10. They loved the show and when I would talk to them about it I was caught up in the action and the dialog. Looking back, it comes across as silly but at that time is was an interesting novelty.
