During season 2 of the Batman television series, Batman and Robin met two other TV heroes in a cross-over adventure - The Green Hornet and Kato! It was a perfect mash-up of two TV properties and a great way to publicize the Green Hornet TV series, plus, we actually get a fight scene between Batman and the Green Hornet and Robin and Kato (Bruce Lee!). Join When It Was Cool for a look back at this cool moment in television history!
