While the comfort, convenience and relative privacy of driving yourself around could be viewed as advantages over public transport, the lack of human interaction has its drawbacks too. For instance, who's going to pull a wacky stunt to amuse their fellow motorists on the freeway? Not only would be that be dangerous, it'd be nigh on impossible to get anyone's attention. But pull your prank on a subway or bus, and you'll have a captive audience.

That's the thinking behind the latest antics by Improv Everywhere. The group that brought you the Starbucks desktop stunt has done it again -- this time employing a group of 10 identical twins to ride the subway dressed in identical clothing. The affect is a human mirror, with one side of the train car an exact replica of the other -- only in reverse (you know, like a mirror).

In my time on public transport I've also seen circus performers, exceptional musicians, and even some decent stand-up comedy. Nothing like a little random performance art to brighten your commute.
