"You're hired!" joke

A guy goes in to apply at the U. S. Postal Service for a job.

During the interview, the interviewer asks the guy if he is a veteran. The guy says "Yes, I fought over in Vietnam."

Then the interviewer asks if the guy has any disabilities.
The guy responds, "Well, I stepped on a land mine over there and blew my testicles off."

"Great!," responds the interviewer... we give disabled Vet preference. "You can start tomorrow morning at 10 a. m."

"But doesn't everyone normally start at 8 a. m.?", asks the guy.

"Yes, but you don't have to come in until 10...
All we do is just stand around and scratch our balls for the first two hours anyway!"
