My feed is overwhelmingly saying Burr was terrible on SNL last night, but I haven't watched it yet but have it on my PVR, and plan to watch later. I'm a big Bill Burr fan, so I'm probably biased, but I thought the opening set was good. Definitely not even close to his best sets, but some funny stuff in there.
