There's nothing like watching a good movie while you're travelling. But one bus driver was left extremely red-faced when he treated his passengers to a different kind of film - after he accidentally left a porn flick running on the vehicle's video player.

A passenger manages to catch the mortifying moment on camera, and the funny footage has gone viral after being uploaded on LiveLeak.com.

It captures the moment the driver realises what he's done when several passengers on board the bus burst out laughing at the X-rated movie.

He can then be seen rushing to the front of the bus to switch it off, pronto.

The faux-pas occurred on a journey from Santiago to Talagante in Chile.

We shouldn't laugh...
