What's the cleverest or funniest scam you've ever heard of? Not necessarily Ocean's 11 stuff but just generally amusing or smart, pulling a fast one.
My favorites include a story I heard about a guy bringing an Irish wolfhound on a flight as a guide dog to avoid customs.

Or another one about guys nicking the licence plate from a speed-van and driving past every speed van they could find at full-throttle.

Any others? Also mod note, this isn't about advocating criminality just the cleverness or humour that can be behind it at times. We all know breaking the law is wrong.
