Elmer says, “Yes sir, I did it three times last night with a 30 year old!”
Leon replies, “You’re kidding! I can’t even manage to do it once! What’s your secret?”
To which Elmer said, “Well, the secret is to eat lots of whole-wheat bread. I’m not kidding!” So the second old man rushed to the store.
The clerk asks the old man, “May I help you?’ “Yes, I’d like four loaves of whole-wheat bread, please,” said Leon.
“That’s a lot of bread! It’s sure to get hard before you’re done!” the clerk remarked.
Leon replies, “Damn! Does everyone know about this except me?”
