A guy goes into the Post Office to interview for a job. The interviewer asks him "Are you a veteran?"
The guy says "Why yes, in fact I served two tours in Vietnam."
"Good," says the interviewer, "That counts in your favor. Do you have any service related disabilities?"
The guy says, "In fact I am 100% disabled: during a battle an explosion removed my private parts so they declared me disabled, it doesn't affect my ability to work, though."
"Sorry to hear about the damage but I have some good news for you, I can hire you right now! Our working hours are 8:00 to 4:00. Come on in about 10:00 and we'll get you started."
The guy says, "If working hours are from 8:00 to 4:00, why do you want me to come at 10:00?"
"Well, here at the post office we don't do anything but sit around and scratch our balls for the first two hours. Don't need you here for that!"
