Jeff is the problem. There was plenty of inappropriate behavior, discussion and language before Andrew ever arrived on the scene.
Vanina seems so sweet and innocent, yet somehow she's ended up working for Jeff. And working for Jeff means your bathroom habits are scrutinized and publicly voiced to the entire staff.
This time around Jeff gets on Vanina's case about allegedly peeing on the seat in such a way that he has to wipe it down. Of course in front of everyone as if he had merely asked her to not CC him on an email or something. At least Vanina was able to muster a quiet, "You're such an ass," after her shaming. (Speaking of shaming, what happened to the smock of shame? Let's bring that one back.)
Luckily for Vanina, she can report to the new HR director, Ms. Jenni Pulos, to lodge a complaint. Somehow we then switch into a very Office-esque mode where Jenni very seriously writes up Jeff for his inappropriate work behavior. Jenni then calls in Jeff whose response is, "Well then you can clean her pee off the toilet seat." Oh the never-ending potty talk at JLD...
