"A Guy was Walking Along the Beach" joke

A guy was walking along the beach in Malibu when he came across this salt-encrusted piece of metal. He worked for an hour or so to remove the salt. Lo and behold, it was a very old oil lamp. The guy started to buff it to remove the verdigris when "poof" a genie appeared.
This genie, like all genies, was so happy to be freed of the lamp that he granted the guy three wishes.
"I wish to be a dollar richer than Bill Gates," says the guy.
The genie wasn't sure who Bill Gates was until the guy told him to check Forbes magazine. When the genie called up Forbes from inside the lamp, he learned that Bill Gates was indeed, the richest man in the world.
"Guy," the genie said, "You will forever be a dollar richer than Bill Gates. What's your second wish?"
"Genie, I want the most expensive Porsche made: Fire engine red, on board GPS and the finest audio system ever installed in an automobile."
"That's easy, Guy," says the genie. He waves his hand and best car anybody had ever seen pops out of the lamp. The genie then asks the guy for his third wish.
The guy mulls the problem over and over. A girl-nah, with billions and billions of dollars he certainly had become a girl magnet. World peace? Only wackos want that. The guy could not find anything that warranted using his third and last wish.
"Genie," the guy said, "I can't think of anything now. May I save the third wish for later?"
"Gee, this is most unusual. But you hold the hammer, and I can't escape from this lamp until you make a third wish. Call me when you're ready," and whoosh the genie disappears into the lamp.
The guy carefully picks up the now-ever-so-valuable lamp and places it in the trunk of the fire engine red Porsche. He turns on the radio to balance the sounds and makes all the other adjustments needed to get his great audio system customized to his ears.
After that, he pulls off the beach and heads south along the Pacific Coast Highway. Soon he's up to 60, then 70, then 80. The Porsche handled perfectly. The guy is so happy that he begins to sing along with the familiar commercial on the radio.
"Oh, I wish I was an Oscar-Mayer Wiener..."
