What does swallowing eyeballs have to do with Frankenstein? Well, to figure this out, we need to take a look at Quan Yin, Queen of Heaven.
I know that each of you out there would quickly gouge out an eye to help out your father. Believe it or not, none of his stingy, worthless, suck-egg-mule kids would do this simple little task to help out dear old dad. I know I'm shocked. Quan Yin is disappointed that times had gotten so bad that children would not do anything for their parents. She created an eyeball and gave it to her father, who swallowed it and could see once more.
In Dean Koontz's Frankenstein, there is a Chinese restaurant that Victor Helios goes to to get exotic food. It seems that when you live for hundreds of years, even Taco Bell gets a little old, so he seeks out the oddest delicacies possible. The dish he is given doesn't have a name in the book. I have since found the name for it as Three Screams. It was live hairless newborn rats served fondue style. I know what you are saying, how does this relate to swallowing eyeballs? The name of the restaurant - Quan Yin.
