My favourite has always been the guys selling X out of the back of their truck, usually AV equipment. Offering ludicrous deals on garbage in expensive boxes with the veil of dubious legality that used to draw people in like flies.

I thought they'd died out but a year ago I was flagged down by a guy claiming to be coming back from a jobsite with a bunch of extra projectors that "no one would miss". Of course the story falls apart when you try to check out the equipment or arrange a later meetup since you're not carrying cash. Points for tenacity I guess.
