Single episode recommendation?

I watched this show years ago and loved it very much. I wanted to show a single episode to my boyfriend, fully aware that he won't watch the whole series, I just want him to see how the acting and the writing was really good. Surely some episodes work better than others for this, so does anyone have any recommendation? Since I last watched it too long ago, if said episode has too much needed context I probably won't recall it either, so a procedural episode would probably work best for this.
