<human>:  Why did George Washington have a wooden leg?
<bot>: George Washington was a very tall man. He was so tall that he could not reach the ground to tie his shoe laces. He had a wooden leg made for him by a local carpenter. The wooden leg was made of wood, and it was attached to his real leg with a metal pin. The wooden leg was used to help him walk, and it was also used to help him stand up straight.
