I'm not sure what's worse, they guy riding and acting like a total douche, or the chick being dumb enough to "come when called" and hop on the bike without a helmet.
I was waiting for biker douche to hop off his bike, walk over and club her on her head and drag her back to his bike caveman style.... I thought the days of "me man, you woman, get over here now because I said so" was long gone.
Not to mention TMZ is just another wart on the ass of society.
