Oh, those are the best kind!
I was so amused in C.H.U.D. when Lauren takes a shower right about the time in the movie there's gonna be a C.H.U.D. attack and I'm just rolling my eyes... and then I realize she just went into some funky sub-basement attached to the NYC sewer system and found a dead cat hung on the wall!
I'd probably take a shower. Like that'd probably be almost anybody's first instinct, actually.
Thought it was really funny that the movie gave Inevitable Badly-timed Shower-girl an actual reason to take the inevitable badly-timed shower.
