If you somehow missed it, consider yourself lucky, as the milkshake inspired thousands of viral videos of… well, it’s tough to explain, but essentially people threw up purple goo all over themselves while becoming possessed by the spirit of Grimace (how else would you describe the plot?).
Because of its virality, it undoubtedly moved a whole bunch of Grimace milkshakes and earned boatloads of free publicity.
