A junior in an office dialed his
boss number by mistake and
said:

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): and do
you whom you’re talking to?
Boss:no?
Junior:thank god.(and disconnected the phone).
