> Forgive my ignorance, but who is Yogi Berra? He seems to get quoted a lot but I've no idea who he is. A baseball
player? Rock musician? Hippy? All three?

Lawrence 'Yogi' Berra was one of the all-time great catchers (the guy dressed like an armadillo standing behind the batsman) in American Baseball and played for the New York Yankees (alongside Joe DiMaggio et al) for almost twenty years before becoming their manager. Despite his colourful nickname he was not named after the cartoon character - rather it was the othere way around! A colleague remarked on the way he walked- 'Just like an Indian nsakecharmer!' The name stuck and the rest, as they say, is arbitrary. I'll leave it to the aficionados to give the statistics.
