Guinness book snubs New Zealand tram-cram August 6, 1998 Web posted at: 5:39 p.m. EDT (2139 GMT) CHRISTCHURCH, New Zealand (CNN) -- During their Thursday lunch break, 143 New Zealanders squeezed and squirmed their way into a city tram in Christchurch's downtown. The townspeople weren't after food. They were after a world record: the most people to pack themselves into a tram car. Christchurch's claim to fame will remain unofficial. The Guinness Book of Records no longer recognizes events that involve people squeezing into small spaces. Guinness says such records promote health risks.
