For some reason, one of my favourite lines is this:
"They say it's raining in New York." McManus, The Usual Suspects
I just think it brilliant sums him up. Keaton has just rolled off a list of reasons why he thinks if they do this job on the boat they'll all die, then the silence kicks in...only to be broken by the pyscho of the group with that line, like he's trying to completely gloss over this fact. In fact, I'd go as far to say that McManus is my favourite character in the film despite my username.
