Blank Check

President Obama walks into the Bank of America to cash a check. As he approaches the cashier he says "Good morning Ma'am, could you please cash this check for me"?
 
Cashier: "It would be my pleasure sir. Could you please show me your ID"?
 
Obama: "Truthfully, I did not bring my ID with me as I didn't think there was any need to. I am President Barrack Obama, the president of the United States of Am ... Erica!!!!"
 
Cashier: "Yes sir, I know who you are, but with all the regulations and monitoring of the banks because of impostors and forgers, etc I must insist on seeing ID"
 
Obama: "Just ask anyone here at the bank who I am and they will tell you. Everybody knows who I am"
 
Cashier: "I am sorry Mr. President but these are the bank rules and I must follow them."
 
Obama: "I am urging you, please, to cash this check"
 
Cashier: "Look Mr.. President this is what we can do: One day Tiger Woods came into the bank without ID. To prove he was Tiger Woods he pulled out his putting iron and made a beautiful shot across the bank into a cup. With that shot we knew him to be Tiger Woods and cashed his check. Another time, Andre Agassi came in without ID. He pulled out his tennis racquet and made a fabulous shot whereas the tennis ball landed in my cup. With that shot we cashed his check. So, Mr. President, what can you do to prove that it is you, and only you, as the President of the United States?"
 
Obama stood there thinking, and thinking and finally says: "Honestly, my mind is a total blank~~~there is nothing that comes to my mind. I can't think of a single thing"
 
Cashier: "Will that be large or small bills, Mr. President?"
