A little old lady was selling seashells on a street corner. One afternoon a well dressed man passed by her, and she grabbed his arm.
"How about some nice seashells?" she asked.
"No, thank you," the man replied.
Suddenly the woman clutched her throat and fell to the pavement,
"What's wrong?" asked the man.
"I'm going fast," the old woman wheezed. "Please buy some shells."
Deeply touched, the man handed over enough money for all the shells just before her eyes slid peacefully shut.
The next day the man was walking down a neighbouring street and saw the woman again vending her wares.
"Hey," he yelled to a nearby police officer, "I thought she passed away yesterday."
The officer smiled knowingly. "Ah, but you were conned," he said. "You see, she sells seashells by the seizure."
