I finally found it...
I saw this movie upon its release, and at the time remember the Bill Paxton quote:
"I bet you're the kinda guy who gets out of the shower to take a piss right?"
I still remember that quote, and it was one that some friends and I used regularly in the early 90's, but forgot where it came from.
Well, I just saw this movie again, and there it is :)
