"Secret Men's Business", Simon Baker, Marcus Graham, Ben Mendelsohn (2002)
The secret to these men's businesses, it seems, is showering naked together (with a good ol' fashioned towel butt whipping). Simon Baker was also in a little-seen Australian miniseries called Naked: Stories of Men (1996) Episode 3 where there was a rugby team shower scene. Does anyone have a copy? I've been dying to find it!
