Season 1 Deleted Scene that proves that it was all planned out ahead of time.

I guess I'll have to eat my hat!

That's what I love about Lost.

I'm not sure when it all started, or whether it was conceived as a form of damage control to the inevitable trainwreck, but some time before the show ended, they produced several parody clips with the original actors and Jimmy Kimmel (played at his show) lampooning the show as it went along.
The crypto speak, the plot, the answers, the authors picking through absurd endings from other shows... just self-deprecation without end.

At least they realize what nonsense they ended up with, and keep making fun of it. Props to them.

(Not that unique, though - the Wachowskis sorta lampooned their story in Path of Neo, and I hear George Lucas likes Robot Chicken - but I'm not familiar with that one)
