ice cream on a rollercoasterIt's easy to begrudge viral marketing when something seems like a ploy meant to trick you. But when the ad is as fun as the one for Cadbury Flake 99, there are no complaints to be had.

That's because, at some amusement park in England or something, people were challenged to eat an ice cream cone going up and down and right and round on a roller coaster, all at over 40 miles per hour. And then it goes backwards!

If we lived there, we'd buy you, Cadbury Flake 99 or whatever!
