The 500-page transcript from the around-the-moon mission details a conversation among astronauts Tom Stafford, John Young and Gene Cernan about one of the more unsanitary pitfalls of the zero-gravity environment, the New York Daily News reported Wednesday.
"Give me a napkin, quick," Stafford said. "There's a turd floating through the air."
"I didn't do it," Young said. "It ain't one of mine."
"I don't think it's one of mine," Cernan said.
"Mine was a little more sticky than that," Stafford said. "Throw that away."
The poop talk eventually subsided until a second piece of waste was found.
"Here's another [expletive] turd. What's the matter with you guys?" Cernan demanded.
