Strange Disease - "mature"

Once there was a woman who began to feel very concerned because her husband was no longer interested in sleeping with her. She couldn't figure out why this was, and decided that maybe there was something physically wrong with her, so she went to see her doctor. After she explained her concerns, the doctor said, "Hokay, take off ah your crows." The woman was a little concerned when she got the doctor's meaning, but she thought, "Well, he's a professional," so she slowly undressed. "Now," the doctor said, "Preez, get down on ah fours, and crawl back and forth acloss the floor." This was even more concerning for the woman, but she really wanted to fix her love life, so she did as the doctor said. As she finished crawling back toward him, the doctor shook his head, frowned, and said, "Ohh, vely selious." Frightened, the woman said, "What, doctor? What is it?!" The doctor frowned again and said, "I'm vely solly - you have Ed Zachary Disease." The woman paled - "Ed Zachary Disease! What's that?!" "Well," the doctor replied, "Your head look Ed Zachary like your ass!"
