Another interesting note about the character was his early appearance. ABC executives did not want to see the Fonz wearing leather thinking the character would appear to be a criminal. The first 13 episodes show Winkler wearing two different kinds of windbreaker jackets, one of which was a colorless green. As Winkler said in a TV Land interview "It's hard to look cool in a colorless green".
Maybe, but it's not so hard to sleep furiously!
