I think the funniest MST3Kish line was said by Dylan. When they opened the box with the two miniature ladies he said, "I thought this was a Godzilla film, but it's Little Women."
We did get to have a science lesson out of all this. I showed the boys that if you double the size of a monster (or anything) you don't double the mass. You don't even square the mass - you cube it! So if a six foot man who weighs 150 pounds were to grow to the size of Godzilla (300 ft), he would weigh 18.75 Million pounds! Then we talked about tensile strength and collapsing into a big pile of goo under your own weight. And for those who are going to poo-poo me for ruining the fantasy for my children, just know that they have a tendancy to let their imaginations run wild after seeing these filsm and our lesson helped assure them that these monsters could not exist and would not crush them in their sleep.
