After nine seasons playing Dwight Schrute on The Office, Rainn Wilson has left that know-it-all behind him... to star as the titular one on Fox's new detective series Backstrom. But when we asked Wilson — who is also serving as Yahoo TV's first-ever guest editor this week — to pick a TV show upon which he's an expert, so that our readers could try to stump him with trivia questions, his mind naturally went right back to Dunder Mifflin.

See how he fared in our inaugural game of Stump the Star in the video above.

For more from this week's guest editor, check out Wilson's picks for Your TV To-Do List and an interview about his new role. We also asked him to solve a few pop culture mysteries, like what actually happened at the end of Lost and to Tony Soprano after the cut to black. Watch him crack those cases in the video below:

Backstrom premieres Thursday, Jan. 22 at 9 p.m. on Fox.
