When the new plastic five pound note came into circulation on 13 September, the first thing people tried to do destroy them.
Not as some strange act of protest, but in order to find out if the Bank of England's boasts of indestructibility actually stood up to the test. And fair play, the big talk proved to be merited.
But now the sad time has come to wave goodbye to the old school fivers, which will not be accepted as legal tender from 5 May.
Not long now.
You can always swap old notes for new at the bank, even after the deadline, but that's no fun at all. If ever there was an excuse to stock yourself up with summer essentials with rubber-banded wads of fivers, it's now.
And gear yourself up for an even bigger spending spree when the new polymer £10 note is introduced in September.
