I would guess that it has happened more than once that someone has said "stompk is that blonde over there." I would further guess that you're just having too much fun to let it wear on you. :-)
What if instead you were bald and you were continally referred to as 'the bald guy'? After all, don't you know you're bald? What's the big deal?
Maybe you'd rather have people referring to your shirt color after awhile... I think you get my point now.
Have fun!
