Try this one - The things people say - it should keep you amused for hours. Funny stuff people have said in all categories, such as courtroom quotes,
stupid package labelling, doctor's surguries, etc, etc....
Another funny one is the Viz magazine website. It has quite a lot of 'crude' stuff on it, I should warn you. But I especially recommend the 'Top
Tips' section.
Another good site for a bit of fun is Net Disaster, where you can load up any page on the web and attack it with all manner of weaponry, from nuclear
bombs to fried eggs or chainsaws. It's all good fun, and doesn't harm anything really.
