When OMWF aired, I watched it so many times for weeks afterwards, that I think I might've went a little overboard...
After the Season Six Finale, all I did from the day it aired until the Season Seven Premiere was watch 'Two To Go' and 'Grave' everyday in between. Literally, everyday - at least 'Grave'.
Last Summer, the one episode I just wanted to watch everyday was 'Restless'. Don't know why, it's just the strange dialogue I suppose. But now I'd have to say 'Conversations With Dead People' is the one episode I'd be able to handle over and over again... if not Restless.
I'm probably going to watch an episode one day and think, 'why the hell didn't I say this episode?'
