Here’s a pretty great commercial/prank set up by Carlsberg, where several unsuspecting couples are sent to a Belgian movie theater with 148 hard-looking not-so-friendly bikers. The gag? To see how people will react. Are they brave? Are they uncomfortable? It’s a pretty nice prank and tells us a lot about stereotypes and our perception of people.

Racists out there could sure learn a thing or two from this. Anyway, if this gag was played on you, how would you react?
