Family Guy is an American animated sitcom created by Seth MacFarlane that premiered on Fox in 1999 and built a large catalogue of short, quotable exchanges. Clips from the show have circulated for years as reaction audio on social media and in edited videos, because the exaggerated deliveries are clear even out of context. This didn't I tell you line follows that pattern, spreading less as a full scene and more as a reusable reaction for moments when an expected outcome happens exactly as someone predicted.
