Ive had alot of weird hair-styles in my life.
Mo-hawks, double mo-hawks, halos etc.
I had a mullet for a week once, but I did that as a joke when me and a friend took a road trip to Georgia. Started as a joke because we were discussing how we would stand out for not having a southern accent and I said "Its cool, ill just sport a mullet and fit right in!" but that went from a joke to a reality/social experiment.
At least hair can be modified, unlike tattoos, but at least I had the foresight to only get ink in areas covered by clothing.
