Didn't read it all comments but seems like a good episode, didn't want spoilers even if not in my current watch list (got many going on and fewer are too serious ones). Offerman and Mullally rock, and even better they seem quite happy together from any bits I've heard.
I bet Shapiro is just jealous of them and found something to screech about for the day. He's all confused about people who can be happy and accepting, not in his nature.
Do want to watch the series still, I never finished the first game even or got far in it. On my list with the show to do at some point.
Also if you want to see early Offerman I recommend the movie Groove which he had a small part as a cop inspecting a rave, back when they weren't commercial so had a fun feel for us racers back then. if that's not your thing I believe he was in a number of sitcoms in the 90s as well, with small parts.
