Hahaha, it's not just the hair, it's probably mostly the kind of character he plays. He is a bit of an oversexed creep as you can see in this short trailer (guy that tries to kiss her on the mouth instead of cheek) I watched a bit of the show today and his character had to show the new interns around the hospital and at the coffee machine, he said he couldn't find the coins in his pocket and he made the cutest girl feel for them in his pockets... creep!
