Zynga recently got some flak from the San Francisco City Attorney’s office for gluing fake $25,000 bills to sidewalks in San Francisco that directed people to the Mafia Wars: Las Vegas website. That was not the biggest marketing stunt for the game, however; not even close.

The social gaming company had a Ustream video of Snoop Dog pushing the button that blew up a fout-ton armored car outside of Las Vegas in celebration of the game’s release. In terms of live streamed events, the Zynga event was surpassed only by Ustream’s broadcast of The Twilight Saga: Eclipse in June. Zynga also gave out 631,000 free virtual armored trucks to users in the game.
