Forbury Lion A hurtful rumour that didn't need posting, even if it was true. Likewise the one about Martin Allen & a players wife, There was one about Jamie Cureton and the Bristol Rover's chairman's daughter too
On the other hand, the internet can be quite good at scotching rumours too. The Cureton one, for example, where it was shown that the chairman didn't even have a daughter.
Of course you still get deluded nutters who believe whatever they want to believe, and people who'll happily give people abuse over things they know aren't true. The sad fact is some people are just daft and think it's ok to say anything "if you're just 'avin' a laugh". I remember some on here slating Chris Tarrant at West Ham for having "no sense of humour" about fans singing stuff about his marriage break-up.
