The Office Season 5 Episode 8 (11/20/08)
Michael is upset when he learns Toby is back as their HR rep. He tries to get CFO David Wallace to get rid of Toby, but Wallace wonders why Michael didn't notice Toby's return for an entire week.
Upon hearing that Toby can only be fired for cause (and Michael saying "it's be-cause I hate him" does not qualify), he schemes with Dwight to frame Toby for a crime he did not commit.
Pam is frustrated when she finds a big mess in the microwave. She writes an anonymous memo on the microwave telling everyone to keep it clean, which nobody seems to care about, save for Angela.
Ryan tells Kelly that they have to break up again because he is allegedly going on a long term trip to Thailand. He asks her to have sex with him one last time and for any extra cash she may have, to which she hesitantly agrees.
It is revealed to the office that Jim bought his parents' house without asking Pam. Jim begins to think keeping it a secret from Pam might have been a bad idea.
