An ambitious Medical Intern in a tertiary hospital dialled canteen & shouted: “Get me a cup of coffee quickly!”

The voice from the other line said: “Youfool! You’ve dialled the wrong extension! Do you know who you’re talking to? I’m the Medical Director of this hospital, you idiot!”

The intern shoutedback:
“And do you know who you’re talking to, you sonofabitch?”

MD: No!
Intern: Thank God! (hung up)
