What scene cemented the show as one of your favorite / greatest shows of all time?

Another post yesterday gave us the delicious memory of "L to the OG", and I think that was the moment the show went from "this is one of my favorite shows" to "this might actually be my favorite show".

I admit I was an easy target, loving Jesse Armstrong's work with Peep Show years before, but this scene just got me in the "heh, they really don't mind doing something purely because it's hysterical (while still driving plot and character)".

So, what's the moment for you where you simply stopped, took a breath, and thought... "This is an all time great right here"?
