A junior in an office dialed his boss's number by mistake & said :
Hey, send a coffee in my cabin in two minutes !......
Boss shouted : do you know whom you're talking to?!!!!!!
... Junior: no!
Boss: i'm the boss of this office.
Junior(in the same tone): & do u know whom you're talking to?
Boss: no!
Junior: thank God.(and disconnected the phone).. ;) :P
