Two French pranksters have created a video showing how men react to having their hand caressed in public by another man.

The video, by Gregory Guillotin and Jonathan Demayo, shows the range of reactions when the men realise it was another man touching their hand.

From indifference to amusement to rage, the pranksters continue the act by winking at the subjects.

The video ends, showing the difference when the men have their hand touched by a woman in public, rather than a man.

It’s quite a contrast, as you’d imagine.
