I`ve got a black woolen hat and it`s got Pervert written across the front of it. It`s the name of the clothing label. And I was with my wife and my baby at the supermarket and I didn`t think. I just put my hat on Clara`s head, because it was cold. And the looks. I couldn`t figure out why I was getting death looks. And then I realized my 10-month old baby`s wearing a hat with the word Pervert written on it and these people were like, `There`s Satan! There`s Satan out with his kid!` And then I made a point of her wearing it every time we went there.
