President Obama walks into the Bank of America and says to a Cashier,
"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 Barack Obama, the President of the United States."
Cashier:
"Yes, sir, I know who you are, but with all the government regulations, monitoring of the banks because of imposters and forgers, etc., I must insist on seeing your 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, but these are government and bank rules and I must follow them."

Obama: "I am urging you to please cash this check."

Cashier:
"Look, this is what we can do: One day Tiger Woods came into the bank without an ID. To prove he was Tiger Woods, he pulled out his putter and made a beautiful shot across the bank lobby into a cup. With that putt, we knew him to be Tiger Woods and we cashed his check."

"Another time, Andre Agassi came in without an ID. He pulled out his tennis racquet and served an ace shot directly into the center of our bank logo 90 feet away. With that spectacular shot, we cashed his check. So what can you do to prove that it is you, and only you?"

Obama stood there thinking and thinking and finally said:
"Honestly, nothing comes to mind. I can't think of a single thing I can do."

Cashier:
"Will that be large or small bills, Mr. President?"
