seashells explained
"screenwriter Daniel Waters, and at a recent Q&A, he was asked about them.
And his paraphrased reply? "I won't tell you the actual secret, but I'll tell you where it came from", he told the crowd after a screening of The Adventures Of Ford Farlaine.
"There's a scene where Stallone has to use a restroom. I'm trying to come up with futuristic things you'd find in there. I was having trouble, so I called my buddy, another screenwriter across town, asked him if he had any ideas. Ironically enough that guy was taking a dump when he answered the phone, looked around his bathroom and said 'I have a bag of seashells on my toilet as a decoration?' I said 'Okay, I'll make something out of that'".
And that, friends, is that. It's not quite a mystery solved, but it's a step in the right direction..."
