They were sitting on their usual park bench chatting. The older one had just finished his morning jog and wasn't even out of breath. The 80 year old was amazed at his friend's stamina. He asked him what he did to have so much energy. The 87 yr old said, "Well I eat rye bread every day. It keeps your energy levels high and you'll have great stamina with the ladies." So on the way home the 80 yr old stops at a bakery. As he is looking around a lady asked if he needed any help. He said, "Do you have any rye bread?" She said, "Yes there is a whole shelf of it. Would you like some?" He said, "I want 5 loaves." She said, "My goodness, 5 loaves..By the time you get to the 3rd loaf it will be hard." He replied, "I can't believe it. Everyone knows about this shit except me."
