Let's try this again.
An elderly gentleman walked into a local barber shop for his regular haircut. As he sat down in the chair, he looked out the window and noticed a man standing on the sidewalk across the street, staring intently at the shop.
The gentleman mentioned it to the barber, "That fellow across the street has been standing there for twenty minutes just staring in here."
The barber glanced out the window, smiled, and said, "Oh, don't worry about him. That's just my twin brother."
The gentleman asked, "Is he waiting for you to finish your shift?"
The barber replied, "No, he's a street performer. He just uses my mirror reflection to practice his mime routine."
