Jack Black got smacked in the face on The Price is Right (video)

"The Price Is Right" launched its 'Celebrity Charity Week' yesterday, and JACK BLACK was on.

A contestant gave Jack a high five after he spun 95 cents on the wheel . . . but his hand kept going and hit Jack in the face.  Jack went down, but obviously he was faking it . . . because that's what a COMEDIC GENIUS does.

The same contestant ended up winning the Showcase Showdown, and he celebrated by giving Jack a big hug.
