A guy goes to the U.S. Post Office to apply for a job. The interviewer
 asks him, "Have you been in the service?"
 
"Yes," he says, "I was in Vietnam for two years."
 
The interviewer says, "That will give you extra points toward
 employment."  And then asks, "Are you disabled in any way?"
 
The guy says, "Yes, 100%... a mortar round exploded near me and blew my
 testicles off."
 
The interviewer tells the guy, "O.K. I can hire you right now. The hours
 are from 8:00 A.M. to 4:00 P.M. You can start tomorrow. Come in at 10:00 A.M."
 
The guy is puzzled and , "If the hours are from 8:00 A.M. to 4:00 PM. -
 why do you want me to come in at 10:00 A.M.?"
 
"This is a government job," the interviewer says. "For the first two
 hours we stand around scratching our balls ... no point in you coming in for that."
