Upon entering the examination room, Dr. Chang said, "OK, take off all your crose." The woman did as she was told.
"Now, get down and craw reery, reery fass to odderside of room." Again, the woman did as she was instructed.
Dr. Chang then said, "OK, now craw reery, reery fass back to me." As she did, Dr. Chang shook his head slowly.

"The woman asked anxiously, "Oh my God, Dr. Chang, what is Ed Zachary Disease?"
Dr. Chang sighed deeply and replied, "Ed Zachary Disease is when your face looks Ed Zachary like your ass.
