This limbo prank is utter genius

Two street performers in Oslo have come up with the best limbo prank.

Holding a limbo pole, they get their willing participants to start limbo-ing while blindfolded. And then they run away, leaving the none-the-wiser limbo-ers pulling all sorts of shapes with absolutely no context.

It's one of those rare pranks that is clever but not mean - just good-natured fun.
