Two guys hear that there is a Deaf Allowance, so they go to the doctor to try and claim it.
The first guy goes in and says, "I'm here to get tested for the deaf allowance"
The doctor says, "Fine, just close the door behind you"
So the guy closes the door and the doctor says, "you've failed."
"What do you mean I've failed?"
"Well I told you to close the door and you did, so you heard me alright. You've failed"
The guy goes out and says to his pal, "look, whatever the doctor asks you to do, don't do it"
His pal goes in and says, "I'm here for the Deaf Allowance" and the doctor says, "Fine, just close the door behind you"
The guy replies, "no...close the f'in door yourself!"
