The internet is chock full of videos designed to see how an unsuspecting public reacts in unusual situations. Well, here's one that definitely touched a nerve.

A British YouTube channel called Trollstation put this video of two actors together in which the man rubs up against the woman while they ride the train to see what the public does in response when the woman gets vocal about the man's groping.

The other people on the train, of course, have no idea the whole thing is being recorded.

The woman has some harsh words for the man, telling him he's assaulting her, while she moves away from him. He follows her before two men get in the guy's face. They were so were so incensed that the woman had to break character to tell everyone he was an actor.

The video certainly made its point and has resonated with scores of people: it has already racked up more than one million views.
