A man with a 25 inch long penis goes to his doctor to complain that he is having a problem with this cumbersome instrument and has had more than one complaint. "Doctor," he asked, in total frustration, "is there anything you can do for me?" The doctor replies, "Medically son, there is nothing I can do. But, I do know this witch who may be able to help you." So the doctor gives him directions to the witch.
The man calls upon the witch and relays his story. "Witch, my penis is 25 inches long and I need help. Can anything be done to help me? You are my only hope." The witch stares in amazement, scratches her head, and then replies, "I think I may be able to help you with your problem. Do this. Go deep into the forest. You will find a pond. In this pond, you will find a frog sitting on a log. This frog has magic. You say to frog, will you marry me? When the frog says no, you will find five inches less to your problem."
