Just in case there weren't enough ways to waste time on the internet...
Surname Profiler reports that there are only 14 Bish's per million people in the UK. A mere 515 of us in the country.
I wondered if there was anyone rarer... turns out our CU leaders speaker and pastor of Above Bar Southampton, John Risbridger is... with only seven in a million. Are you more rare?
Forget google-whacking, are you one in a million? (The system only records those where there are over 100 people with the name... so if you're one in a million you wont show up, but two should... )
UPDATE: My best man is a Harwin, only five in a million.... as is my mate Mr Carding.
