Hasta La Creative!

What better way to cap off the year in which agencies were obsessed with prankvertising than with an agency pranking its own staff?

Baltimore shop Planit created the amusing video below after luring unsuspecting employees to sing holiday songs on camera. When a Leatherface-masked elf jumps out of the large present next to them, their reactions range from sprinting panic to cool-headed indifference.

There's not much more to it than that, but the wide array of staff responses make it worth a watch. Planit also deserves points for giving the clip a strategic message, ending with the kicker, "We believe the best ideas should scare you."
