Season 4, Episode 9: "Dinner Party"
Oh, to have been a fly on the wall at this spectacularly uncomfortable dinner party. Steve Carell's Michael Scott is in fine form, with his visibly pained grin frozen on for the majority of the episode, which puts his dysfunctional relationship with Jan front and center. With every strained "babe" they exchange with one another, the tension between Michael and Jan bubbles up at a smartly timed pace. You're on the edge of your seat, wondering what the ultimate breaking point will be, and during the hysterically awkward 22 minutes, we're treated to some amazing factoids, like Jan's side hustle creating candles and Michael's prized possession, a plasma TV with a display that's not much bigger than a laptop screen, and the fact that he will sometimes "just stand here and watch television for hours."
