Bill Hader! Much as I love Doc and Jackson's voice-over work, it's nice when they can expand the cast. I think he makes a good replacement for Colbert.
I didn't think they could make me give a shit about Phantom Limb again, but they proved me wrong. This episode reminded me of "Home Insecurity" from Season One, what with the four intersecting plotlines. Nice to see Hank is actually good at something, while Dr. Venture continues to be a complete tool. And the end sting was f'in fucking spectacular.
