Rotten Cherry

This old lady was complaining to her friend about a little problem she had with vaginal itch. Her friend suggested that maybe she had an STD. The old lady replied "that's impossible because I am a virgin". To solve the problem the old lady went to the doctor for check up. After the exam the doctor said: "I have good news and bad news, the good news is that you are clean of all STD'S. The bad news is that you have fruit flies because your cherry is rotten"
