A guy goes to 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 to 4. Come on in about 10, and we'll get you started."
The guy says, "If working hours are from 8 to 4, why do you want me to come at 10?"
"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!"
