What I'm Not Doing

Some people think that all I've done since I arrived is play tennis (see comment posted by Johnny on Customer Service). If you look closely, you'll discover that I'm neither of the people in this photograph. I don't play tennis, and don't intend to start. Please leave it now.

However, I do know enough about tennis to be certain that the position of the receiver is going to leave him in trouble if the serve goes to his backhand.
