Zach Galifianakis first “Saturday Night Live” hosting appearance was maybe one of the funniest things I’ve ever seen (“That’s so Raven?”), so I had high hopes for his second stint this weekend. Alas, the show was off-kilter and random, and not in the good way Zach is generally known for. But one sketch in particular made me crack up — watch as Zach plays a dragon costume-clad “Game of Thrones” fan on the show “Game of ‘Game of Thrones’,” who keeps getting the, well, hardest questions for a “GoT” fan to answer. Jaime Lannister himself makes an appearance. Swooooon!
