San Antonio Mayor Julian Castro loses prep boys' basketball wager, dyes hair blond

At this point, San Antonio Mayor Julian Castro must be tired of losing basketball bets.

Less than a year removed from being forced to walk the streets of Miami in a Heat jersey after his Spurs lost in the NBA Finals, Castro lost an equally embarrassing wager to a local Lanier High student-athlete who challenged him to dye his hair blond if the school's boys' basketball team made the playoffs.

Well, the Voks (25-7) won nine of their final 10 games, captured third place in their district and qualified for Tuesday's bi-district round of the Class 4A state tournament, and the Mayor lived up to his word, participating in the team's 15-year-old tradition of dying their hair blond for the postseason.

Castro, who delivered the keynote address at the 2012 Democratic National Convention, tweeted a photo of himself at the school's pep rally over the long weekend (h/t MaxPreps). In addition to stressing the value of both living up to his word and illustrating his support for the local youth, he came prepared with a joke (via KSAT-TV): "Well, I don't know if blonds have more fun, but they seem to have more fans."

But the line of the day went to his twin brother, U.S. Congressman Joaquin Castro, who told KSAT-TV, "He looks like a character out of a James Bond movie." Silva from Skyfall, to be exact. And this photo of the identical twins offers a reminder of what Julian Castro looks like with his natural hair color.

The Mayor will reportedly lose the blond look at his wife's behest before Lanier tips off against Buda (Texas) Hays High on Tuesday. As for these friendly wagers, Castro is giving up on predicting basketball games, choosing instead to take a jab at his city's NFL neighbor to the north: "The only bet that I'm going to make in the future is that the Dallas Cowboys win the Super Bowl, and I think I'll be safe."
