A man with a crippling stutter visits his doctor hoping for a cure, he walks into the doctor's office and says:
The doctor gives him a thorough physical examination, and sure enough discovers the problem....
"D D D D Do it!"
So they prep for surgery and very quickly the operation is performed. A complete success, the man leaves for home delighted to be cured. But that night his wife finds out what he did. She is very unhappy and urges him to reverse the surgery.
And so the next day the man arrives back at the doctor's surgery.
But the doctor replies...
"N N N N N N No Refunds"
