^The crossover was weird. The Green Hornet and Kato were presented as real within Batman's universe... even though Batman
existed as a TV show within the Green Hornet's universe. Plus the GH & K had made a prior window cameo in a Batman
episode wherein Batman recognized them as fellow crimefighters, but now he thought they were villains.
(And will someone please explain to me what stamps and alphabet soup have to do with each other thematically?)
