Have you ever seen a snail up close? Have you ever seen a snail eat?
They're cute little things, but also very strange. Mollusks are pretty different from human mammals, so it's not surprising that some people find them a little freaky.
Watch this little guy snack away:
According to some guy on the internet, it tickles when a snail nibbles you. "It's like a free cleaning service. Nomming away my dead skin."
Do with that information what you will.
