Meredith Grey: Please raise your hand if you ate any cookies from this tin. Unfortunately, the cookies in this tin were tainted with rat poison. So we need to treat those of you who have ingested them as soon as possible, please.
(They get everyone into one room…)
Meredith Grey: Okay. False alarm. The cookies had marijuana in them.
Catherine Avery: What?!
Meredith Grey: Yes. I didn’t want to scare you.
Jackson Avery: So you went with rat poison?
Arizona Robbins: You scared me to death.
Jo Wilson: What?
Meredith Grey: You knew they had weed in them.
Arizona Robbins: Right. Yeah. I-I forgot.
