There's a spec ad running around the web right now, touting the clean emissions from the Audi A5 by demonstrating a mans failed suicide attempt. You must have seen it, even AgencySpy showed it off. Would be good for the spec director and/or creative team if the credits ran around the web with it.
However, the idea isn't all that new. Back in 2002 there was a spec ad touting the clean emissions from a Citroen, directed by the king of dark comedy Brian Baderman.
Citroen - Suicide - (2002) :45 (UK)
The Audi "krass" spec commercial:
Audi A5 - Suicide / Krass - (2009) :60 SPEC
Please note: SPEC work means that the ad was not bought by or approved by Audi
