When his son refused to get a job, his father insisted he join the Marines.
At the induction physical, the doctor directed the reluctant recruit to read the eye chart across the room.
"What chart?" The young man asked.
"The one on the wall!" The doctor said.
Sensing he had a deadbeat on his hands, the doctor asked his nurse to walk in with a poster of an extremely beautiful woman beyond anyone's possible measure.
"What do you see now?"
"Nothing" said the young man.
"Well, you may not see anything," the doctor said, "but your 'indicator' is pointing toward Paris Island!
Welcome to the Marine Corps, son."
