A patent medicine salesman at the fair was shouting his claims for his Rejuvenation Elixir. “If you don’t believe the label, just look at me,” he shouted. “I take it and I am 300 years old.”
“Is he really that old?” asked a farmer of the salesman’s young assistant, Mulla Nasrudin.
“I REALLY DON’T KNOW,” said Nasrudin. “YOU SEE, I HAVE ONLY BEEN WITH HIM FOR 180 YEARS.”
