I just wanted to add this one, especially as a historical reference. It is a cancelled throwdown -- yes, such a thing can happen!

In this one, there were only two entries, one of which was DQ'ed toward the end of the voting
because it was not even cooked. That's right, and despite it being raw, it still garnered 25% of the votes! What I love about this is the discussion that eventually leads to comment #29. No, please don't read ahead and ruin it. It's best to go through the thread comment by comment until you get there. It's only a couple pages and well worth the wait!
