All due respect to Arlington Mayor Robert Cluck. Really. But something seems out of whack when the mayor of San Francisco has to make the requisite mayor wager with a guy in Arlington. If the Rangers win, Cluck gets Dungeness crab, sourdough bread, Ghirardelli chocolate, and Anchor Steam beer — all excellent comestibles and potables. If the Rangers lose, the San Fran mayor gets Spring Creek BBQ, which TMZ says is “said to be the best in Texas.” Um, no. Not really. It’s not even the best in Dallas. Or Arlington. Whatever.
