A man applies for a job with the US Postal Service, and is invited for interview. The interviewer says "I see you've spent some time in the military. That will count in your favour, since this is a government job. By the way, have you been anywhere interesting?" "Yeah" says the man, "I served in Vietnam". "What was that like?" asks the interviewer. "Well," he says "it was pretty grim. I got captured and tortured. During my torture they surgically removed my testicles!" The interviewer is shocked but impressed. "Ok," he says "I'd like to offer you a job - the hours are 8am to 6pm Monday to Friday, I'll see you at 10am on Monday." "Hold on" says the candidate "you just said the hours are 8am to 6pm. Why don't you want me to come in until 10am?" "Let me explain" says the interviewer "this is a government job. When we come into work in the mornings we sit around for 2 hours scratching our balls, and there's no point in you turning up for that!!!!"
