Rye Bread ?

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, but me.”
