Sid and Al were sitting in a Chinese restaurant.
"Sid," asked Al, "Are there any Jews in China?"
"I don't know," Sid replied. "Why don't we ask the waiter?"When the waiter came by, Al said, "Are there any Chinese Jews?"
"I don't know sir, let me ask," the waiter replied and he went into the kitchen.
He quickly returned and said, "No, sir. No Chinese Jews."
"Are you sure?" Al asked.
"I will check again, sir." the waiter replied and went back to the kitchen.
While he was still gone, Sid said, "I cannot believe there are no Jews in China. Our people are scattered everywhere."
When the waiter returned he said, "Sir, no Chinese Jews."
"Are you really sure?" Al asked again. "I cannot believe there are no Chinese Jews."
"Sir, I ask everyone," the waiter replied exasperated. "We have orange jews, prune jews, tomato jews and grape jews, but no one ever hear of Chinese jews!"
Arm replantationIn 1962, a 12-year-old boy's severed arm was reattached in the world's first successful replantation of a human limb with microvascular repair of vessels by a team of surgeons led by Drs. Ronald A. Malt and J. McKhann at the Massachusetts General Hospital, Boston. The arm had been severed three inches below the shoulder by the wheels of a train. Good functional recovery of nerves is generally better in children than in adults. After additional operations, he regained some useful functioning of the limb. A journal article in Nov 1969 gave in a case report that he recovered a powerful grip and strength in his biceps muscle. Though there was a little “clawing” of the fingers, his tactile recovery was good enough to identify coins and use his fingers in handling objects. He became employed as a garage mechanic.«
