For me, The Ring... 2002-ish.
I usually only go out for 2 or 3 hours once a week, and that's more than enough for me. This week we made an exception and also went to see the Book of Mormon (the most hysterically funny thing I've seen in my life), meaning I could technically spend a year or two w/o going out amongst the living and not even think about it.
However, I think I'll celebrate the occasion by watching it in the study/man cave. :) I've been in a Beatles kinda mood lately.
