New, via Finland. NSFW-ish (no nudity)
The AIDS Council of Finland draws you in with sex, and then jars you using Facebook "Places" as a creative linchpin (Penis-pin? [Sorry]). The spots are quite effective, I think.
This is the TV execution of a print campaign (here's one of the print ads, NSFW) from earlier this year. The TV is more powerful.
Ad agency: McCann.
