Don't put that pen in your mouth
I remember one of my elementary-school teachers would scold kids for chewing on their pencils. I can't remember if I chewed on my pencil, but I did like to cover my hand with glue and then peel it off like it was an extra layer of skin.
But that's getting off the topic. The point of this post is to let leachers know that there is a new way to keep kids from chewing on their pencils or pens:
Make them use the Cow Patty Pen.
Yes, one cow's excrement is one man's fine writing instrument.
