Just watched the DVD version of the Aristocrats. It was one of the funniest jokes ever and each person telling it really changed the joke immensely. However if your sense of humour if even a bit under very good and if you can be easily disgusted by references to strange things, then forget that I wrote anything, or just watch it anyway to try to overcome that :)
Warning: do not in any circumstance allow a republican, anyone with a weak heart, or a child under 21 hear anything from that piece - you'd risk radical democratisation, a death stroke or a head filled with REALLY strange thoughts respectively.
Otherwise, just have fun and try not to die laughing :D
