A bet is a bet. And Pau Gasol faces the music when he loses one.
The Lakers center, along with his brother Marc, a center for the Memphis Grizzlies, teamed up with the Boys & Girls Clubs in L.A. and Memphis for what they called the "Healthy Competition 2013."
The competition involved children from both cities striving to see which group would have a healthier summer. Apparently Memphis won, because Marc Gasol gets to keep his beard, while Pau had to shave his.
He posted videos of the event to YouTube... see below. For more information on the Gasol brothers' charity, go to GasolFoundation.org.
