Years ago, I had a co-worker who claimed to have seen video of this conversation between then-ABC White House correspondent Sam Donaldson and President Ronald Reagan. The conversation went like this:

Donaldson: Mr. President, are you aware that 80% of American men masturbate in the shower, and the other 20% sing?

Reagan [coldly]: No, Sam, I didn't know that!

Donaldson: Yes, sir. And do you know what song they sing?

Reagan [clearly annoyed]: No, Sam, I don't!

Donaldson: I didn't think so.
