There is an 80 year old virgin who suddenly gets an itch in her crotch
area. She goes to the doctor who checks her out and tells her she has
crabs.
She explained that she couldn't have crabs because she was a virgin, but
the doctor didn't believe her so she went to get a second opinion.
The second doctor gave her the same answer.
So she went to a third doctor and said "Please, help me, this itch is
killing me and I know I don't have crabs because I'm a virgin".
The doctor checks her out and says "I have good news and bad news. The good
news is you don't have crabs, the bad news is that your cherry rotted and you
have fruit flies."
