A Government Job

A guy goes to the Post Office to apply for a job.
The interviewer asks him, 'Are you allergic to anything?'
He replies, 'Yes, caffeine.'
'Have you ever been in the military service?'
'Yes,' he says. 'I was in Iraq for two years.'
The interviewer says, 'That will give you 5 extra points toward employment.'
Then he asks, 'Are you disabled in any way?'
The guy says, 'Yes, an IED exploded near me and I lost both of my testicles.'
The interviewer grimaces and then says, 'O.K. You've got enough points for me to hire you right now. Our normal hours are from 8:00 A.M to 4:00 P.M. You can start tomorrow at 10:00 A.M. and plan on starting at 10:00 A.M. Every day.'
The guy is puzzled and says, 'If the work hours are from 8:00 A.M. to 4:00 P.M., why don't you want me to here until 10:00 A.M.?'
This is a government job,' the interviewer says, 'For the first two hours, we just stand around drinking coffee and scratching our balls. No point in you coming in for that.
