My favorite Buzz thing-- aside from the time he busted that guy in the chops for asking him if the moon landings were fake-- was when Letterman was sending him out and about in the world for a while. He went to the daytime emmys in his astronaut suit and did red carpet interviews.
Which would go like this:
Buzz: Hi there! Who are you?
Soap Star: I'm Mr. Soap Star, and I'm nominated for best hooha in a thingy.
Buzz: That's great. I walked on the moon.
(very awkward silence)
I would love to watch that; now that's television!
