His imitation of the "spoilerphobe" is probably the best part of this video.
But I have to admit, I'm probably a less exaggerated version of the kind of person Conan and Homeland actor Damian Lewis are talking about here. I hate being forced to race to watch or play something just to avoid getting spoiled on it by an overly excited fan on the Internet. But as one of its denizens, I have to accept my lot in life and know what places and conversations to avoid.
They still kind of have a point, too. You can't expect years to go by and still be able to call "spoilers!" out rationally. There's a certain acceptable timeframe in which spoilers are unfair, even if we all probably haven't agreed on one yet. And not everything constitutes a spoiler, though as a writer on the Internet I've learned to be very, very careful about labeling spoilers. One man's concept art is another man's hell.
