ironychan has been posting book and movie commentary this weekend over at her webcomic Dumnestor's Heroes. One of today's thoughtful suggestions was "If you want to kill an afternoon, I recommend a back-to-back viewing of [Bruce Campbell's Army of Darkness] and the 'Battle of Helm's Deep' section of 'The Two Towers". Every time you get the urge to quote one movie during the other, take a shot. You'll be reeling before the credits roll."
I'm a non-drinker, so the alcohol part wouldn't apply, but what an intriguing comparison.
