Ed Zachary Disease:

A woman was very distraught at the fact that she had not
had a date or any sex in quite some time. She was afraid she
might have something wrong with her, so she decided to
employ the medical expertise of a sex therapist.

Her doctor recommended that she go see Dr. Chang, the
well known Chinese sex therapist. So she went to see him.
Upon entering the examination room, Dr. Chang said, "OK,
take off all you crose."

The woman did as she was told.

"Now, get down and craw reery reery fass to odder side of room."
Again, the woman did as she was instructed.

Dr. Chang then said, "OK, now craw reery reery fass back to me."

So she did.

Dr.Chang slowly shook his head and said, "Your probrem
vewy bad, you haf Ed Zachary Disease, worse case ever see,
dat why you not haf sex or dates."

Confused, the woman asked, "Oh my God, Dr. Chang,
what is Ed Zachary Disease?"

Dr. Chang looked the woman in the eyes and replied,

"Ed Zachary disease is when your face rook Ed Zachary rike your ass."
