squid beak

Hi! During one of my science talks on cephalopods at the Dutch Natural History Museum I was asked by a young child how an octopus brushes its teeth. I thinks it's a brilliant question. Of course, I explained that all cephalopods have a beak, but then I kept wondering about the real question...

Does anyone know a good way of removing all of the meat from squid and octopus beaks? Greg
