Harry Peters went to the Canadian Post Office to interview for a job.

The interviewer asked him, "Are you a veteran?"
 
"Yes, I served two tours in Vietnam."  

"Good, that counts in your favor. Do you have any service
related disabilities?"

"I am 100% disabled. A mortar round blew off my testicles 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 8am  
to 4pm. Come on in about 10am, and we'll get you started."

"If working hours are from 8am to 4pm, why do you want me
to come at 10am?"

"Well, this is a government organization. We don't do anything but sit around and scratch our balls for the first two hours. No point of your coming in for that"
