I was riding in the car with my 7 year old daughter, Mariah, and she asked what I was playing with. I explained to her that it was a gyroscope for strengthening my forearms. She said "Oh" and got quiet for a few minutes. I watched her in the rear view mirror, and she appeared to be deep in thought.

Finally, she said "Daddy?". I replied "What?". She got a big smile on her face as she exclaimed "You don't have four arms!"
