Lice
Meredith:Hurry up already.
Erin:[checking Meredith's head] Trust me, I know what I'm doing. Between the foster homes and the orphanage, I had lice 22 times.
Erin:Holy wow, that's a big one. Alright, pencils down everyone, we got lice!
Angela:Oh God, Meredith, lice? Did you not sign a pledge to shower?
Dwight:What? Lice? Oh my god. Lock the doors, we are on full quarantine.
Pam:Dwight, relax. It's just lice. Maybe, possibly.
Dwight:Just lice Pam?
