Unsuspecting people get their pants pulled down by the fastest pranksters in the world (Video)

Pranking is a real art form.

You had Trigger Happy TV that used to troll everyday Brits with flashes of genius like the giant snail crossing the road or the loud mobile phone guy. Then there was faux gangsta Ali G that reeled in celebrities and politicians like the late Tony Been, who was seething over his mock misogyny. This next clip isn't going to win any Prankster of the Year awards - it's probably the lowest form of prankery that there is. But that doesn't make it any less funny. In fact its childish simplicity makes it all the more hilarious. It's literally a guy pulling down people's pants or slapping pedestrians with custard pies - only so quick they don't know what's hit them. Yes, okay, we need to grow up...
