Which EP? Door-Used-As-a-Desktop sightgag

IIRC... It was a later-season ep. IIRC, the gag was Fitzy(?) sitting in his office at a desk, and the camera pulls back to reveal his "desk" is merely an old door repurposed as the top of a desk. Perhaps in relation to a discussion of financial-something. Possibly with Brent. Possibly with Fitzy(?) saying he's actually not much better off financially -- like: Hello, my desk is just an old door (eg, on cinderblocks, etc. Don't remember it specifying.)

Can any CG savants halp?

Just remember LMAO at the time. But despite rewatching a good number of random old episodes from time-to-time since, I haven't managed to run into this scene in years. Thanks. :)
