LOST season 1, episode 19
Definitely one of my favorite moments from the first season of lost.. This is the part where John Locke is trying to figure out how to get into the newly discovered hatch. He's out there pounding on the hatch one night trying to figure out what it all means, then suddenly the light comes on.. so dang good. I've started to watch lost again and it's pretty funny to be reminded that 99% of the questions on this show never get answered and that most of the time you have zero idea what's going on.
Ha, metaphor for life I guess
