Late Show with David Letterman - Season 9 Episode 151 Kid Scientists, Allison Janney, Al Green
Nine guys in Spider-Man outfits, not to mention Dracula, Superman, and a cowboy cram themselves into a Subway restaurant; Tony Orlando dresses down Dave even though he interrupted him, then leaps into a chorus of "Knock Three Times"; when one of Lee Marek's kid scientists starts a very flammable demonstration, Dave demands that the band and everyone else onstage take for cover behind his desk.
