Jenna has updated her TV Guide Blog here. Here's a snippet of tonights episode:
This week we bring you “The Carpet,” written by the brilliant Paul Lieberstein (who also plays Toby). In this episode, someone leaves a “gift” on the carpet in Michael’s office. It’s soft. It’s smelly. It’s brown. It is the exact same gift you wish you could leave in your boss’ office. The question is: Whodunit? Everyone is a suspect. Michael is determined to find out. To keep a close eye on the office, he takes over Jim’s desk, forcing Jim to work at an empty desk near Kelly. Jim quickly learns why Kelly works in the back by herself.
Sounds hilarious :)
