In a famous restaurant on the Baker street, a crowded night in the city. A strange man walks in and announce he can identify any kind of wine with a blindfold on. The challenge was immediately accepted. With a cloth over his eyes and wine after wine, he sipped a bit and would announce "Le Chateaus la Claire, 1978", or " Bernkastaslaka du Wachis, 1956"... He was always right.!
After a while someone handed him a glass he couldn't identify, he sipped, and then sipped again, and drink a little bit more, and would swallow... but couldn't seen to identify it. Suddenly he pat it out and pulled off the blindfold.
He yelled,"What the hell! This is Urine! Fresh Urine!" "Yes," said a voice in the background ," but whose?".
