Friend of mine had their bike nicked and was advised by the Police to visit two local car boot sales, and ring them when he found it. Sure enough there it was....the guy had innocently bought it (and the other two which were also stolen) in a pub... Police knew he was lying, but couldn't prove it. Still bike was recovered.
Our local one is even funnier... Trading Standards let it be known that they would be visiting, an surprisingly there were far fewer cars there.
Funniest thing is that they had actually been the previous week, and were looking to see which regulars had avoided being there the week they were officially attending. They (along with the Police) then targeted these individuals and prosecuted about a dozen for counterfeit, unsafe or stolen goods. One was a local electrics firm shifting the stuff they couldn't sell in the shop as it was electrically unsafe.
Personally wouldn't touch one with a bargepole.
