The thing I remember most was him giving the example of the checks of British sailors being used as currency in Hong Kong bars, and the statement that having the reserve currency is great... it's like writing checks that no one cashes. Until one day you have a crisis of confidence and then everyone cashes their checks at once.

It's a great visual, and I try to imagine all the treasury bills floating around outside the USA and when they will flood back domestically to be cashed... a tsunami of paper promises
