Post Office Joke

John goes to the Post Office for a job interview.
The interviewer asks him, "Are you allergic to anything?"
He replies, "Yes - tea."
"Have you ever been in the military service? "Yes," he says, "I was in army for two years." The interviewer says,"That will give you 5 extra points towards employment." Then he asks,"Are you disabled in any way?" John says,"Yes. A bomb 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 8:00AM to 4:00PM You can start tomorrow from 10:00AM every day." John is puzzled and asks, "If the work hours are from 8:00AM to 4:00PM, why do you want me to start here from 10:00AM?" "This is a government job," the interviewer says, "For the first two hours, we just stand around drinking tea and scratching our balls. No point you coming in for that."
