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
meto 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!"
