I have always believed that something is not a world record just because no-one has thought of doing it before (cf Big Brother 2 and the stupid sugar lump tower). So “breaking” the record for the highest dinner party is not a proper record in my book.
Andy anyway, couldn’t this easily be beaten by having a dinner party IN A PLANE! On A SPACE SHUTTLE. Surely it cannot be a dinner party unless Dido is on the stereo and people are talking about the rise in house prices. NONSENSE!
