The Prime Minister of Australia Julia Gillard walks into a Perth bank and asks to cash a cheque for $2000..
Teller: "No problem madam. Could you please show me your ID."?
Gillard: "Well, I didn’t bring my ID with me as I didn't think there was any need. After all, I am the Prime Minister, Julia Gillard"
Teller: "Yes, I know who you are, but with all the regulations, I must insist on seeing ID."
Gillard: "Just ask anyone here who I am and they will tell you. They all know who I am."
Teller: "I am sorry, but these are the bank rules and I must follow them."
Gillard : "Is there some other way around this?"
Teller: "Look, here's what we can do: a while ago now, Greg Norman walked into the bank without ID. To prove he was Greg Norman he pulled out his putter and a golf ball and trickled it ten metres across the floor into a cup. Then we were sure he was Greg Norman and cashed his cheque.
Another time, Pat Rafter came in without ID. He pulled out his tennis racquet and lobbed a tennis ball fifteen metres - right into my coffee mug. After that spectacular shot we cashed his cheque.
So, what can you do to prove to me that you are really the Prime Minister of Australia?"
Gillard stands, deep in thought for what seems like minutes then finally says: "My mind's a complete blank. Honestly, I can't think of a single thing"
Teller: "Would fifties be OK, Prime Minister?"
