Ben's near-death and Jin's return to the living are among this season's thumps.

Happy Thumpday!

As Lost catches one last breath this week before unfurling the final four episodes of Season 5, we thought it a good time to assess the 13 end-of-episode "thumps" served up thus far.

Review below the list of moments that wowed us before the screen went to black, and then vote for the one that slammed you deepest into the sofa (or beanbag chair, if you've been appropriately channeling the '70s).

Feel free to elaborate on the thump you're stumping for in the comments section.
