I'm all for individuality, I truly am—if you want a mohawk, you should rock the hell out of one.
After all, it's your life and you only get one of them, so do your thing.
That said, if you do choose to rock a mohawk this insanely large, please don't be offended if people out there (me) think you probably should have gotten over the mohawk phase in high school, when you were drumming in a wannabe-NOFX punk band with your buddies.
