I've had lots of people, usually men, ask me who he is. I've learned to counter, "Who do you think?" It makes for interesting conversation.
One man cogitated for a long while, and said "Could be Clint Eastwood."
"Could be," I said, but it isn't."
He looked a while longer. "I know who it is!"
"Who?"
"It's me!"
"You got it."
