Do You Chew On Your Pen?

Is it a nervous habit or do you do it because you are bored? My teacher always said "DON'T CHEW ON YOUR PEN"!

Personally I don't see a problem with it and we have all done it but at least now the pens will taste better! This guy is now making edible pens out of candy with edible ink! COOL! Check this link! http://www.ohgizmo.com/2011/03/29/edible-candy-pens-make-it-ok-to-chew-on-them/#
