Louie has the "NO PIGGIES" command. When he was a puppy we used to play "this little piggy" with his paws.... He is allergic to grass so his little "piggies" get itchy and he will itch them and lick them. He sometimes does this if he is bored too.

Funny thing is if he's licking our toes and we say "NO PIGGIES" he stops immediately. At times he's just too smart.
