Thin and Fat

Once there were two sisters. One was fat and ugly and one was thin and beautiful. The fat ugly sister got lots of dates, but the thin beautiful sister never got asked out. She didnt understand it, so she decided to go to the Chinese doctor down the street. He looked down her throat, then asked her to drop her panties. He looked up her ass, then looked down her throat again. The beautiful sister asked: Doctor Wu, did you find my problem? Doctor Wu replied: Im afraid you have the Zachary syndrome my dear. Upset at this news, the sister asked in a shaky voice: The Zachary syndrome! What is the Zachary syndrome? Doctor Wu replied: Your breath smells zachary like your asshole!
