Query: Laugh it Up

The last episode of this season alone makes the disc worth the money. Beyond that, the classic 'Dinner Party' episode is the shining light of this season. There are some great character arcs for Kevin, Toby, and Dwight, and the subplots with Ryan run throughout the season, culminating in a terrific surprise. Of course, Steve Carell's portrayal of Michael Scott holds front and center in this season, and his glue holds everything together like mayo holds tuna salad.
