8 XXX : extramile

Not really my cup of pee.
Repeat with me (as sing be Seal): “I (I) Have (Have) Pissed on a rose in a scene...”....
She looks like Diane Keaton
Is she under duress here? What’s the reason for not hiking the skirt high enough to avoid peeing on it?
I believe that for every drop of piss that falls, a flower grows.
I gotta have that movie, can anyone link to that?
There's a great freeuse scene in tis movie too
I actually have this DVD, but have never watched it. Had it for ages, too.
Can someone tell me the context behind this? What makes this scene significant for the movie?
