A man came to the emergency room

A man came to the emergency room with a series of long, jagged tear marks on his cheek and neck, as though he had been clawed by some large animal.

“What happened to you?” asked the doctor who was examining him.

“Chain saw accident,” the man replied.

“Well, you’re lucky,” the doctor said; “I’ve seen worse.”

“It wasn’t turned on,” the man replied.
