UPDATE: Better make that a Smirnoff.
Stoli is distributed in the US by Pernod Ricard, the French company that recently acquired Absolut. Anyone thinking of boycotting Pernod Ricard over this ad (which might yet prove to be an April Fool's Day joke) had best check their liquor cabinet.
UPDATE II: It's looking legit.
Here's the same ad on a billboard (via Michelle Malkin).
UPDATE III: Think these will be Photoshopped much?
UPDATE IV: Another billboard shot here, posted three weeks ago.
UPDATE V: This eBay listing says the ad is from 2007.
