Boris needs to cash a cheque and approaching the cashier says, “Good morning, could you cash this cheque for me?”

“It’s my pleasure. But first I need to see ID?”

“I didn’t think that was necessary. I’m the Prime Minister.””

“We have banking regulations and Rules are Rules”

“Everybody knows me.”

“I’m sorry but I must follow banking regulations.” 

“I am urging you. Please cash this cheque.” 

“There is something we can do. Tiger Woods came in without ID. To prove his ID he used his golf club to make a beautiful shot into a cup of tea held by the bank’s chairman. We immediately cashed his cheque.”

Johnson stood there thinking and thinking and finally said, “Honestly, my mind is a total blank. I have absolutely no idea what to do.”

“That’s fine sir. Large or small notes?”
