Second chance winners?

Has there ever been a contestant on a reality show competition who got voted out, kicked off, evicted, chopped, the tribe spoke, was not the biggest loser, was the weakest link, got fired, or whatever...and then got a second chance to battle it out and won (within the same season)?

I'm not talking about coming back for a second time in another season. But within the course of the same game, for whatever reason, came back to the tribe, boardroom, house, kitchen, whatever?

Thanks!
