& it hurts too!
They have some big teeth for a small snake, and they don't like to let go, because it's a feeding response & not defensive.
The best thing to do is keep some tequila on hand (or your other favorite hard liquor) - a few drops in the snake's mouth usually gets them to let go rather quickly - a shot for the victim helps too.
Cheers (literally),
