Job at the Post Office

A man applies for a job at the Post Office. The interviewer asks him, “Are you allergic to anything?”
He says, “Just caffeine”
“Have you ever been in the service?”
“Yes,” he says. “I was in Iraq for two years.”
The interviewer says, “That will give you five extra points toward employment,” and then asks, “are you disabled in any way?”
The guy says, “Yes, an IED exploded near me and blew my testicles off.”
The interviewer tells the guy, “Ouch! That had to have hurt. The good news is, I can hire you right now.”
“Normal hours are from 8 AM to 4 PM. You can start tomorrow at 10:00 – and plan on starting at 10 AM every day.”
The guy is puzzled and asks, “If the hours are from 8 AM to 4 PM, why don’t you want me to be here before 10 AM?”
“This is a government job,” the interviewer reminds him. For the first two hours we stand around drinking coffee and scratching our balls. No point in you coming in for that.”
