Found on the internet, so it must be accurate:

After I heard him play in concert, Ray Charles asked me whether or not I’d like to come back to his room. Of course, I would! He went on in ahead of me, and the place was pitch black. I followed the sound of his voice, until he entered his bathroom. Then my eyes adjusted to the dark just enough for me to realize he was shaving!

Do you know how it is when you don’t really mean to say something out loud, but the words just come out anyway? Well, that’s what happened. I said, “Ray, why are you shaving in the dark?”

He said, “Turn on the light.” I did.

Then he asked, “Feel better now?” —Bill Cosby
