Doggie style
A young lady went to the doctor for her annual physical. The doctor told her to undress and sit on the examining table.
She did as she was told and when the doctor turned around from his desk to examine her he noticed two big scabs on her knees.
He said, ” My god what happened to your knees?”
She said that they were caused by doing it doggie style.
The doctor gave her some ointment and said that until the scabs healed up she had to turn over and do it in the missionary position.
She said she would like to but she couldn’t stand the dog’s breath.
