Simpsons Did It

What you say when you overhear someone plotting revenge as an allusion to Dougie from South Park who said it repeatedly to Butters

Carrie: "I took a Louisville slugger to both headlights, slashed a hole in all four tires, and carved my name into his leather seat to avenge my ex-boyfriend for cheating on me".
Karen: "Simpsons did it!"
Miranda: "I walked into a bar and attacked his new girlfriend because I'm an immature little girl who can't get over my ex like he got over me".
Karen: "Simpsons did it, Simpsons did it!"
Carrie: "They did not!"
Karen: "I know. I'm just saying what Dougie said to Butters whenever he plotted revenge against the people who wronged him".
Miranda: "South Park is a stupid show. The main characters think hunting is stupid, so I hate that show".

you did what needed to be done

The ultimate compliment which can be bestowed. Most appropriately used when serving looks to legendary children. Popularized by the television series Legendary and used liberally among YouTubers Peter Monn and Munoz (kinda).

Pam: Honey, that look is a ten out of ten.
You did what needed to be done.
