A friends walks up to the porch to say hello, and hears an awful yelping, squealing sound coming from inside the house.
"What's that terrifying sound?" asks the friend.
"It's my dog,"said the farmer."He's sitting on a nail."
"Why doesn't he just sit up and get off it?" asks the friends.
The farmer deliberates on this and replies:
"Doesn't hurt enough yet."
