Though the situation IS amusing I tend to think that no celebrity should be 'chasing down' anyone in this regard. Ignore them, mock them maybe or whatever but the 'bad boy' crap should get him fired from whatever job he's working on. People who choose a occupation that puts them in the public spotlight need to be able to control themselves better.
Now if Hayden would have chased the guy with his elbows tucked closely to his torso but the rest of his arms mincing wildly and yelling a girly "Nnnnoooooooooooooo!!!!!".... THAT would have been worth seeing.
