I have heard of people who get tattoos of their favorite company's brand logo, have massive collections of a particular product, or maybe have a themed wedding based on the company. I have met some FTers how love to visit the UA company store whenever there a Do at an UA facility. I do admit to having a small collection of old menus, model planes, etc, but no tats.
Let's hear from the ones of you that are in the extreme fanboy/girl realm.
