GUERRILLA BREXIT: English Vigilantes Use Ladders, Sticky Letters to Exterminate the Metric System.

Tony Bennett took Brexit preparations into his own hands at dusk one Friday this month, defying authority to reinstate a venerable element of British culture.

All it took was glue and stick-on numerals.

The retired lawyer crept through a park, he said, and up to a footpath sign. It read “1.5km.”

Unacceptable!

He took a numeral and pasted it on to make the sign read, simply, “1.” That’s one mile, one glorious British imperial mile, rounding up a bit. No need to add an “m,” Mr. Bennett said, because Britons would know what it meant.

“We have our own very excellent system of weights and measures,” said Mr. Bennett, 70 years old and not the American crooner. “We don’t need big institutions in Europe telling us what to do.”

Mr. Bennett is a member of Active Resistance to Metrication, a tiny group that has for years been pushing England to go back to its old weights and measures. Britain’s planned exit from the European Union has breathed new hope into his campaign.

Godspeed.
