Wow, this is seriously hard.

Can we just end the round right now and name all 4 the winners? Seriously, they're all that bad.
But, I'll give the #4 spot to "The Marble Armrest of Xerxes." This Green Monkey team was slow, incompetent, and did NOT deserve to go to the temple. They seriously gave it no effort whatsoever all run, and they only won the temple because their tiebreaker question was easy. However, their layout was just impossible. They had to go all the way around the bend just to get to the armrest. So victory was hopeless anyways. That alone gives it
some excuse, compared to the Top 3 still remaining. Those runs however, had NO EXCUSE for their losses. So I feel #4 is a good stopping point for Marble Armrest.
