pea-sized bologna

I was reading the back of my toothpaste tube yesterday so that I could enlarge my dental hygene data base. I had honestly never read the "Directions" on the back of the tube and I had some time to kill so I took a look at what Crest had to say about brushing your teeth. Did you know that they instruct you to put a "pea-sized" amount onto your brush? I mean come on. Really? Here we are trusting the health of our canines and molars to a company that measures the accurate amount of toothpaste in vegetable sizes. Is this some kind of conspiracy? Do Crest and DelMonte have some sort of deal in this?
