Some nodes are really entertaining to read, because of the merit of the content, or because the responds that go beyond, I believe, the expectation of the OP. In the latter case, my reaction doesn't go towards to the OP, in that, I'm not laughing at him/her. It's just so, well, entertaining, without any intent of insulting or anything else. Below is what I've found so far, in no particular order:
I'll place this list on my homenode, and I think I can expand it from yours. So I'd like to know what everyone's list of entertaining nodes, ones you find amusing from any aspect, ones you'd like to read over and over. This is one of things I do here when I have nothing else to do, no question to ask or answer, and no nodes to vote on. That is, entertaining myself.
