Two guys, one 80 and one 87, were sitting on their usual park bench one morning.
The 87-year-old had just finished his morning jog and wasn't even short of breath. The 80-year-old was amazed at his friend's stamina and asked him what he did to have so much energy.
The 87-year-old said, "Well, I eat rye bread every day. It keeps your energy level high and you'll have great stamina with the ladies."
So, on the way home the 80-year-old stops at the bakery. As he was looking around, the lady asked if he needed any help.
He asked, "Do you have any Rye bread?"
She replied, "There's a whole shelf of it. Would you like some?"
He said, "Oh yes, Il take 5 loaves."
She admonished, "My goodness! 5 loaves? By the time you get to the 3rd loaf, it'll be hard."
He replied, "I can't believe it. Everybody knows about this shit but me."
