Two old guys, one 70 and one 75, were sitting on a park bench one
morning.
The 75-year-old had just finished his morning jog and wasn't even short
of breath.
The 70-year-old was amazed at the guy's stamina and asked him what he
did to have so much energy.
The 75-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 70-year-old stopped at the bakery. As he was
looking around, the saleslady asked if he needed any help. He said,
"Do you have any rye bread?" She said, "Yes, there's a whole shelf of it.
Would you like some?"
He said, "I want five loaves."
She said, "My goodness, five loaves! By the time you get to eat the 3rd
loaf, it'll be hard."
He replied, "I can't believe everybody knows about this shit but me"
