"Well," replied his old friend, laughing. "It's simple really. I eat rye bread every day. Lots of it. It keeps my energy level high, especially with the ladies, if you know what I mean."
Gerry did know what he meant and decided there and then that it was time for a drastic lifestyle change. He bid his friend good-bye, and walked to the nearest bakery.
"What can I get you?" asked the lady behind the counter.
"Do you have any rye bread?" asked Gerry.
"Yes, there's a whole shelf of it. How much would you like?"
"I want five loaves."
"My goodness, five loaves!" exclaimed the lady. "By the time you get to the 3rd loaf, it'll be rock hard."
"Sheesh!" said Gerry. "How come everybody knows about this except me!?"
