CAPTION THIS: San Francisco Mayor Ed Lee Shows Detroit Mayor Dave Bing Twitter Headquarters

Though the World Series showdown this October petered out after four games and had record low TV ratings, things got pretty heated in the teams' hometowns of Detroit and San Francisco. Even the cities' two mayors, Detroit's Dave Bing and SF's Ed Lee, waded into the fray, -- each agreeing to a bet that the loser would have to go to the other's city for a day of service.

“[Lee's] going to have to leave his heart in San Francisco, because if he brings it here, we’re going to step on it,” Bing, Detroit mayor and former basketball star, said in advance.

It was a pretty good burn, even if he did have to eat his words after the Giants easily swept the Tigers.

Though Bing and Lee may have traded some trash talk during the World Series (your HuffPost Detroit and SF editors couldn't help ourselves, either) we're glad to see there's no hard feelings between the two local leaders.

Instead, Lee hosted Bing on a tour of the Bay City, during which the two talked to youth in San Francisco and led him on a tour of tech businesses. Bing last week said he was eager to bring back some lessons from California to apply to Detroit.

Given Detroit's recent aim to become the startup capital of the Midwest, Bing certainly had a thing or two to learn from the home to Silicon Valley. In fact, he seems entirely baffled as Lee points something out from the rooftop garden of Twitter's headquarters.

While the Associated Press caption has Lee and Bing taking a "look at nearby construction," we can't help but imagine other possible exchanges between the mayors of these two very dissimilar cities. We're sure you, dear readers, are thinking along the same lines.
