wyz raises an interesting point though. Look at movies like the Jungle Book. The snake is evil. Look at Aladdin. Jafar has a snake on his staff. Hell, even look at the bible for those of you religious folk out there. Satan appears to Adam and Eve in the form of a snake.
It's everywhere. Kids are being bombarded with imagery that shows nothing but evil, wretched snakes. So of course they will grow up associating these fairy tale characters with real life snakes.
