Here's further proof that you don't need celebrities, scantily clad models, or even a developer's conference to advertise a product. Playing up those billboards that rotate through multiple advertisements during the day, Samsung stuck one of its vacuums on top of this sign, and it roars to life with suction whenever another ad attempts to rotate into place.
You have to assume that Fiat is in on the gag too, because it's an ad for the company's 500 that keeps getting sucked out of frame. If not, they'll know soon enough as this clever campaign spreads. [YouTube via Taxi]
