When Dick Findley and Pete Conrad found out about Nixon scratching the Apollo Space program (as mentioned in "Lunacy", an episode of 'Law & Order: Special Victims Unit'), it was rumored that Conrad would have been on Apollo 20. In Toobworld, we can assume Findley would have been on it as well.
Here are some pertinent lunar nuggets about Conrad from Wikipedia:
Charles "Pete" Conrad, Jr. (June 2, 1930 – July 8, 1999), was an American astronaut and the third person to walk on the Moon. He also described himself as the first man to dance on the Moon. He served on Gemini 5 and 11, Apollo 12, and Skylab 2 missions, and may have been scheduled for the Apollo 20 mission, which was cancelled.
In the 1995 film Apollo 13, Conrad was played by David Andrews. In the 1998 HBO miniseries From the Earth to the Moon, he was played by Peter Scolari (in episode 1, "Can We Do This?") and by Paul McCrane (in episode 7, "That's All There Is").
"If you can’t be good, be colorful.” Pete's personal motto.
