Finally, I got the DVDs of all Apollo flights from 7 to 17, the last one being Apollo 14.

For 14, there's a radio broadcast (press conference) before the flight where a woman journalist asks the question:
Are you planning on doing or saying anything unusual during the flight?

Shepard hesitates, doesn"t answer annd asks: what do you mean?

She says: well like reading Bible verses?

Sheparf answers: there are no plans to read or quote Bible verses.....

That must have been a relief to him to be able to answer that way as he knew he was going to play golf on the Moon but won't tell anybody.
And Mitchell could still hide his ESP experiments.

Those unusual things seem always to be the ones they least wanted to talk about beforehand, and people most remember afterwards.
