A pint-sized piece

Did you know that a British imperial pint holds about 20 percent more beer than a typical American pint? Somehow I missed this fact during my junior year abroad. (Probably because I had never had an American pint, being underage and boringly law-abiding.) And because the Brits are a bit uptight about weights and measures, regulations dictate exactly what fractions of a pint pubs may serve: One half or one-third, nothing more or less. But it looks like they might be relaxing a bit this year, allowing for a two-thirds pint. Cheers!
