What does a pair of buzz shears have to do with bringing bipartisanship to Washington?

Sunday on " This Week with George Stephanopoulos," two party flacks are setting aside their differences by settling a hair-raising political bet - and it all benefits a good cause.

Before the presidential election, Democratic National Committee spokesman Brad Woodhouse made a bet with his Republican counterpart, Sean Spicer, at the Republican National Committee. The deal: Whoever's candidate won the election would shave the loser's head, on national television.

But rather than let Spicer go bald alone, the pair decided to team up to support the St. Baldrick's Foundation, a national group that raises money for childhood cancer research grants by shaving the heads of volunteers.

They've both agreed to lose their locks for charity, and - with a little razor help from ABC's Jon Karl - you can catch their hair-raising transformation Nov. 25 on "This Week."

"After the election, I was excited that I'd be shaving Sean's head instead of him shaving mine," Woodhouse wrote on his online fundraising page. "But, when we learned about St. Baldrick's, we decided that we should BOTH shave, making our bet pay off for kids fighting cancer."

The non-profit St. Baldrick's Foundation has raised more money for childhood cancer grants than any other group, second only to the federal government, according to Lisa Parks, senior director of advocacy. To date, the foundation has raised more than $101 million, and they're up to more than $33 million this year alone.

Though they're both getting sheared, Spicer and Woodhouse are still about the competition: They've each set individual fundraising goals - Spicer at $5,000, and Woodhouse at $1,500 - to support childhood cancer research.

"Bread and Sean have really picked up on this, and they're taking it to a whole new level," Parks said. "It's such a positive thing to have happen in the political world."

Spicer, who lost the bet after Republican presidential contender Gov. Mitt Romney conceded the election to President Barack Obama, said the shave-off is about more than just politics.

"We're not just honoring a bet," Spicer wrote on his fundraising page. "We're having our heads shaved to stand in solidarity with kids fighting cancer, but more importantly, to raise money to find cures."
