Mad Bum, the underwear, is already here

Here's what you get when you're the MVP of the World Series, besides a free Chevy truck: your own pair of underwear.

Sort of.

Jockey has quickly made 2,000 pairs of limited-edition "Mad Bum" underwear to commemorate the third World Series championship won by Madison Bumgarner, the San Francisco Giants pitcher, who tossed one shutout and saved the final win.

"MadBum" is his nickname.

Alas , the unusual underwear — imprinted with the words MAD BUM across the backside — is not for sale. But it will be carefully distributed by Jockey to Giants fans at the city's parade on Friday celebrating the World Series championship.

"We wanted to provide fans with a fun, eye-catching keepsake in support of Madison's postseason greatness," said Dustin Cohn, CMO of Jockey International, in an e-mail.

The Jockey street team already passed out hundreds of pairs to fans Wednesday night at AT&T Park and the city's public viewing of the game at Civic Center. On Friday, it will be passing out thousands more at the San Francisco parade along the official route on Market Street.

But Bumgarner is hardly the first hero to step into a Jockey promo. Jockey, in an offbeat ad campaign that rolled out in August, is taking the celebrities in skivvies concept to the next level by showing off bona fide American heroes in their briefs. Such as Gen. George Patton. And baseball great Babe Ruth. And, yes, even veteran astronaut and moonwalker Buzz Aldrin.

While Bumgarner hasn't appeared in an actual Jockey ad yet, it's being discussed.

"Madison Bumgarner is one of the all-time postseason greats with a name that's a perfect fit for the Jockey brand. We're proud he wears Jockey and congratulate him on a third championship," said Cohn.

Online, Jockey is promoting a 30% off men's sport underwear sale for those who use this code: MADBUM.
