"If I made a movie..."

We were strolling leisurely back to our vacation rental, ice cream in hand (or Italian ice in my case, thank you milk allergy) satisfied after a good competitive game of miniature golf.

"So, this was nice, wasn't it?" I asked the family.
"YEAH." Joshua said, emphatically, "It sure beats sitting at the condo listening to music or watching bad girl teen dramas on television."
"Or Animal Planet."
"Thank you, Joshua, " I said, "for wrestling the remote from your sisters this afternoon."
"I KNOW!" He said, "I couldn't take 'Victorious' one more second. I mean, all those shows are the same!"
"HEY!" piped up Ruth. "I LIKE Victorious."
"But the plot is always the same: 'I'll hook you up with one of my friends and then it will all go wrong and in the end we should have just talked about it anyway," Joshua said in his 'girly voice' impression.
"Soooo," Ruth said.
"Oh, and 'GUY' shows and movies don't have the same plot?!?" I asked. "Oh, let me chase the bad guy in a car, and then shoot everyone, but I'm the good guy so I won't get even a graze when the bad guys shoot at me with automatic weapons, and in the end something HUGE has to be blown-up: a skyscraper, a helicopter, a 747..."
"Actually," Jeremy interrupted, "It's more like, the bad guy tries to kill the good guy with some elaborate and overly complicated scheme and then says 'Well, since you're going to die anyway, let me tell you my nefarious plans,' and then he leaves allowing five or more hours for the good guy to escape when in reality a bullet to the head would have allowed him to continue on in his evil merry ways."
"This is true," I replied.
"And in fact," Jeremy continued, "It's been documented there are only so many plots in the world, and everything is a variation within."
"Really?" The kids asked.
"So they say," Jeremy said.
"But what if I came up with my own plot?" Ruth asked.
"It would still be a variation of one of those documented," I replied, "According to this theory."
"Not if I made a movie," Hannah chimed in. "If I made a movie, it would be totally random. It'd start with a picture of lard, and then there'd be a duck, and it might come and eat the lard. I'm not quite sure about that part just yet."
"Yup, That'd be totally random, Hannah," I said.
"Did she said Lard?!?" Ruth asked.
"Lard?" Joshua said.
"And a duck," Hannah said. "Don't forget the duck."
