You might want to take a look at "Are You Dave Gorman?" the true story of a British comedian called Dave Gorman who as the result of a bet set out to find as many other people by the same name as possible, and ended up with 54 of them (including several people who changed their names!). It's VERY silly...
Later edit - forgot to say that there's a Wikipedia article about it, since there was a TV show, stage show, and book about it.
