Stan 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 the armed forces for three years'. The interviewer says, 'That will give you extra points toward employment' and then asks, 'Are you disabled in any way?' Stan says, 'Yes, 100%. A mortar round exploded near me and blew my testicles off.' The interviewer says, 'OK, I can hire you right now. The hours are from 8:00am to 4:00pm. You can start tomorrow. Come in at 10:00am.' Stan is puzzled and says, 'If the hours are from 8:00am. to 4:00pm, then why do you want me to come in at 10:00am?' '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.'
