Yesterday my older sis sent me a funny ppt. on this odd hairstyle. Now, I don't know anybody personally who sports a mullet, I still have a theory about its appeal:
It has the same shock-value of really big obnoxious tatoos, without all the expense, pain or permanance.
ADDED: For those who haven't seen me in a while...
This is not a picture of me! I am white, skinny and possibly disreputable looking. But this is just a picture I harvested off of the internet tubes. dbp
