(via) If you're a whip-smart Mad Man like me, you see the joke coming (well, I knew ahead time it was an ad for Stride gum) almost immediately. What I didn't see coming was the eww! ending. EWW! Spoiler Alert! Watch the video first. Done? OK—she chews up dead husband ash! I want a client like Stride gum! Ad agency: JWT NY, who, three years ago, posted a "pre-owned Stride Gum" ad on craigslist. Related: the most elaborate gum commercial ever produced.
