I have now wasted about 2 and a half hours of my life thanks to you and TV Tropes. Not quite your 4 hours, but still. It was all completely new to me, so I just had to follow link after link (like Wikipedia but much, much worse). Metaphorgotten, Deadpan Snarker, Wangst, Unfunny, Woobie, Nightmare Fuel, Narm, and even Petting Zoo People. It's so satisfying to see these things given names, and then to see examples that you know (like that Wesley torture scene in Princess Bride under Nightmare Fuel). Oh, and I almost forgot Uncanny Valley! That one has so many "OMG yes!" examples, and a really great explanation of the phenomenon.
