Rye Bread Humor...

So I found this joke online... its a bit dirty but I couldnt help myself! since my dad has the most perverted sense of humor I figured this joke was perfect! My parents came in for the weekend to visit me at my apartment in NYC so for breakfast I surprised them with a family favorite... rye bread, smoked salmon and scallion cream cheese... Could we be any more Jewish?? Here goes... Enjoy!

Two old 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 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 5 loaves.'
She said, 'My goodness, 5 loaves... by the time you get to the 5th loaf, it'll be hard.'
He replied, 'I can't believe it, everybody in the world knows about this shit but me.'
