Two friends decided they would dodge the draft by having all of their teeth pulled. They knew the army would not take them if they were toothless. Finally, the day came where they were to report to the draft board. As they lined up they were separated by a big truck driver who had obviously not bathed in weeks. When the first friend stood before the sergeant for a physical examination he told the sergeant that he had no teeth.
The sergeant ran his fingers around his gums and said, "Alright, you have no teeth -- you're 4F."
Next came the big, smelly truck driver. The sergeant said to him, "What's wrong with you?"
The truck driver replied, "I have a terrible case of piles."
The sergeant inserted his fingers in the truck driver's ass, and felt around, and said, "Yep, you've got piles. You're 4F."
Next came the second friend, and the sergeant said, "What's wrong with you?"
The recruit stared at the sergeant's finger and replied, "Nothing sir, nothing at all."
