Krista Vernoff is credited with the introduction of the catchphrase, seriously into the dialogue of Grey's Anatomy episodes. Series creator Shonda Rhimes says that Vernoff used it frequently in the writer's room, and "said correctly, it can convey sarcasm, dismay, disbelief, a sense of moral and ethical superiority, and gentle chastising punishment, all at once."
