German pen company Stabilo, much like a 16 year old boy sorting through the girls in gym class to choose the one who will fuel his masturbatory endeavors while trying to fall asleep that evening, has crafted an ad only a 16 year old boy would appreciate. Oh who are we kidding? Every guy from 8 to 108 will love this ad. After all, when it comes to certain thoughts, behaviors and desires, guys never really grow up.
