OK, now these casting leaks are just getting weird. But still good-weird. I hope.

Variety reports that billionaire investor Warren Buffett will join the long list of celebrity guest stars slated to appear in the upcoming Office season finale. He’ll pop in for a cameo as one of the many people applying for Michael Scott’s vacant regional manager position, alongside the already reported Ray Romano, James Spader, Catherine Tate, Ricky Gervais, Will Arnett and Jim Carrey. Kathy Bates will also appear in the episode, “Search Committee,” as Sabre CEO Jo Bennett.

Variety sheds some light on how and why Buffett got hooked in — apparently, he owes them a favor:

Buffett enlisted the “Office” cast for a skit shown in April at the annual shareholders meeting for his company, Berkshire Hathaway. Carell appeared in the skit, in which Buffett pretends to take over for Michael Scott as the head of the Scranton branch of fictional “Office” company Dunder Mifflin.

So he’s already got some experience pretending to apply for the job! Good thing, because I’m sure Warren Buffett needs plenty of practice suspending his own disbelief that he’d want or need a regional manager position at a measly paper company.

The finale airs next Thursday, May 19. Last week in “Inner Circle,” Will Ferrell’s obnoxious Deangelo Vickars vacated the position after an unfortunate interaction with the warehouse’s basketball hoop. This Thursday, Jo (Bates) returns to temporarily sort out the vacancy, and the title of the episode says it all: “Dwight Schrute, (Acting) Manager.” Here’s a sneak peek photo from Thursday’s episode:
