I'd say this one was the weakest episode so far this season, especially the end, terrible attempt at a joke at the end.
A few good visual gags but it was way too predictable.
Nice to see the Flying Spaghetti Monster doubting evolution, not super funny but amusing, I think that's the problem, evolution is just not a good topic for comedy anymore, been done to death, same with the nano-bots evolving, been done way too much although they really took it all the way this time.
