I literally heard Steven Wright - the comedian - say something like that once. It was in St Thomas. I didn't want to bust his secret as I saw he was with family on vacation, but my buddy wasn't as compassionate. He asked him across a parking lot, "Hey mister...are you Steven Wright?!" ... Steven calmly replied in his very boring monotone stage voice "Yes. Yes I am.". At the time, it was hilarious.
... but maybe I just laugh too easily..idk.
