If it weren't for the Dale subplot which went nowhere and sadly wasn't that amusing, this would've been a solid A. I really enjoyed the Bobby/Hank/Peggy interaction; it felt like a return to earlier episodes when they were the main focus, only updated so that Bobby was a bit more mature than he was in those season 1 shows.
The characterization was spot-on; Bobby's stuck in that awkward period when he's not quite ready to grow out of his old habits, doesn't want to stay out all Friday night and be fully independent, as we saw when Hank and Peggy lost track of time and forgot to pick him up. At the same time, he clearly didn't want to be best friends with his parents. Peggy feeling guilty and over-compensating Bobby the morning after felt very natural, too.
Most of all, I think we can all relate to this plot. There comes a point in our lives when playing board games with the folks just doesn't cut it anymore, and I think we've all been in situations when the parents were a bit late in picking us up, and our trust in them is questioned.
It wasn't their LOL funniest episode, but I don't think it was intended to be. It was about Bobby growing up. That said, there were some funny moments:
-"Peggy and I haven't been on a date since... (thinks) Huh."
-Bobby talking about game night, and one of his peers says, "You really like your parents. That's so gay."
-Bobby alternating between appreciative (Peggy) and scornful looks (Hank) when Peggy says it was Hank's fault they were late.
-"I'm watching prostitutes buy pantyhose!"
-Hank on the ski arcade machine.
