This was a funny commercial.
I wonder if Dave Goelz actually operated Bunsen here. Something about his movements seem different.
I also wonder if Kermit was only here to include one of the main Muppets. I think it could have worked with just Bunsen and Beaker (and they're certainly not obscure characters). I guess the main thing Kermit added to being there (aside from introducing) is telling Bunsen that Beaker is on fire.
I wonder if we'll get more commercials anytime soon that star supporting characters. It'd be great to see a commercial with The Electric Mayhem (or just a few members... I don't really want to see one with just Animal, though), or a commercial starring Scooter.
