Two very elderly men were having a conversation about sex.

Elmer says, Yessir, I did it three times last night with a 30-year-old!

Leon replies, Youre kidding! I cant even manage to do it once! Whats your secret?

To which Elmer said, Well, the secret is to eat lots of whole-wheat bread. Im not kidding!

So the second old man rushed to the store.

The clerk asks the old man, May I help you?

Yes, Id like four loaves of whole-wheat bread, please, said Leon.

Thats a lot of bread! Its sure to get hard before youre done! the clerk remarked.

Leon replies, Damn! Does everyone know about this except me?
