I’ve never been able to find a copy of one that I saw only once, years ago, in the middle of the night. It was a “use condoms/prevent STDs” ad. Near as I can recall, here’s how it went: a couple, man and woman, are in bed together, clearly about to make the eight-legged aardvark. Camera pulls out, and the bed is huge, a giant expanse of rumpled sheets, and it’s filled with other people, who begin to crawl toward the couple. Finally, they’re all together in one big mass. The couple looks down, and attached to their ankles are shackles, connected via clear tubing with shackles on all the other people. A red fluid begins to ooze down the tubing, showing that they’re all connected by blood. And, that was pretty much it.
Things don’t get much more disturbing and hard-core than the ads by the Montana Meth Project. They’re all here; in particular, I think the “Boyfriend”, “Mother”, “Friends”, “Parents”, “Just Once”, and “That Guy” ads are good.
