The Last Supper

Why do people on death row get a last meal? I mean, if you know your gonna die in a few minutes, would you be able to eat anything, much less keep anything down?I read this book of Texas Death-row inmates and what their last meals' were. Yes, they have a whole book on that! One guy asked for two buckets of KFC, a double bacon cheeseburger, four lobster tails, a whole pizza, a bowl of spaghetti, a twelve pack of beer, a carton of cigarettes, a whole cheesecake...and a toothpick. Heaven forbid he goes to the chair with shit in his teeth! The book didn't say if he ate it all. With that much meat, I'm actually wondering if all the electricity in his body would have brought the animals back to life....like you see the guy frying and all of a sudden 5 lobsters crawl out of his ass and a cow hoof comes out of his mouth. thats quality tv right there!
