STAFFORD: Who did it? [laughter]
CERNAN: Where did that come from?
STAFFORD: Give me a napkin quick. There’s a turd floating through the air.
YOUNG: I didn’t do it. It ain’t one of mine.
CERNAN: I don’t think it’s one of mine.

YOUNG: What the hell is going on here?
And that’s why we need a space program. Save NASA!!
