A funny man who just appeared opposite Charlize Theron in Young Adult will guest star in the Feb. 27 episode of "Two and A Half Men."

And the lucky guy who gets to play the ex-business partner of Walden (Ashton Kutcher) on TV’s top-rated comedy is:

Patton Oswalt!

I can't help it, but whenever I think of Patton Oswalt, the first thing I think of is this guy (http://kimpossible.wikia.com/wiki/Professor_Dementor).

The Internet billionaire's first business partner, Billy -- played by Young Adult's Patton Oswalt -- will swing by his newly purchased Malibu abode with a new get-rich-quick plan he can't do without Walden.

Billy's arrival doesn't sit very well with Walden, who -- judging from the photos here -- isn't thrilled to see his former partner. It turns out that after the former partners, who started their business in Bridget's garage, sold it for billions, Billy went off the deep end and the pair had a falling out.

So how does Billy get in the door? Turns out Alan (Jon Cryer) has dollar signs in his eyes and sees himself as being the beneficiary of Billy's new billion-dollar idea and takes a bribe to set up the meeting.

Check out the photos below. Oswalt's Two and a Half Men episode, titled "The War Against Gingivitis," airs Monday, Feb. 27 on CBS.
