This is a really easy one for me, because there's only 1 castaway that makes me die laughing every time they open their mouth...
Shane Powers.
Oh my god Shane... I don't see why he hasn't come back yet, he is absolute GOLD. From the Thinking Seat to his Blackberry, even when he gets blindsided he goes out with another classic moment that is probably my favorite blindside reaction of all time. Shane easily made Panama the great season that it was, and the fact that he is only a 1 time player is an absolute travesty.
