Zynga may have thought they were being uber-clever with their guerilla marketing efforts for their game Mafia Wars, but the city of San Francisco was not amused.

To promote the online game, Zynga glued dozens of fame $25,000 bills to the sidewalks in various locations around the city - bills the Department of Public Works is pissed at having to steam clean off the ground.

Enter San Francisco City Attorney Dennis Herrera, who has plans to make Zynga an offer they can't refuse. According to the SFGate, the city wants Zynga to turn over all its information about the guerrilla marketing campaign, asking for "emails, work orders, scope of work, contracts, marketing plans or other records -- that show when and where the graffiti in San Francisco was placed, and by whom," Deputy City Attorney Alex Tse wrote to the company.

Apparently simply paying for the cleanup won't be enough, officials said.

The underdogs put up a fight (and damn it was close), but in the end, San Francisco and New York - the two #1 seeds - advanced to the finals of America's Best Ad City.

New York - 56% to Portland - 44%
