The following transcript details a conversation between Charles Duke and John Young during an Apollo 16 mission in 1972.

Young: I got the farts again. I got the farts again, Charlie. I don't know what the hell gives 'em to me... I think it's the acid in the stomach, I really do.

Duke: It probably is.

Young: I mean, I haven't eaten this much citrus fruit in 20 years. But I'll tell you one thing. In another 12 f---ing days, I ain't ever eating any more!"
