I enjoyed this episode. However, the start made my head hurt. It's a crossover with Bob's Burgers that's basically one long inside joke that both Bob and Archer are played by Jon Benjamin who uses his real voice for both. Since nobody (including me) has seen Bob's Burgers, I have no idea if there were references I was missing from that, though.
Otherwise, there were some well-worn tropes they reused, but it was solid nonetheless. I remember thinking last season started weak and then picked up so I can't complain about the start here.
