This is a viral ad for DHL shipping that involves pranking the other major shipping companies by using them to send giant chilled boxes with heat-reactive printing that reads 'DHL IS FASTER' when warm. Sure, clever prank, but still -- poor sportsmanship. I didn't know the shipping industry was such a mug-slinging campaign. You want me to tell what shipping service is the best? They all suck. If you want something to arrive on time and unbroken you'll have just as much luck shooting it out of a cannon.
Keep going for the video.
Thanks to Tim and Side Effect, who have both seen employees from every major shipping company kicking boxes down the sidewalk.
