Porpoises

   	A man had a friend who owned 2 very intelligent porpoises. They could do
	amazing tricks, and communicate with humans very well. After much urging, 
	the owner agreed to sell the porpoises to his friend. "But remember this," 
	said the seller: "The porpoises will never die as long as you feed them each 
	one live seagull every day. As soon as you miss a day, they will die."

   	The new owner transported the porpoises to his home, and placed them in his 
	outdoor swimming pool, where he kept them alive and well for some time.  Each 
	day he would go down to the beach, capture 2 live seagulls, and bring them 
	home to feed to the porpoises.

   	One day as he was returning home with a live gull in each hand, he found a 
	lion lying across his doorstep, basking in the sun. He became panicked,
	because he knew that if he didn't get through to feed the porpoises, they
	would die. So he jumped over the lion and ran quickly into the house.

   	Inside, much to his surprise, were two FBI agents who promptly placed him
	under arrest. "What's the charge?" asked the stunned porpoise owner. "What
	have I done wrong?"

   	"You, sir," replied one of the FBI agents, "are being charged for illegally 
	transporting captive gulls across a sedate lion for immortal porpoises!"
