A guy goes to the 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 three 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 10:00A.M." The guy is puzzled and says, "If the hours are from 8:00A.M. to 4:00 P.M. then why do you want me to come in at 10:00A.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."
