Remember? He used to want to be someone else every time and always got in trouble? Example: Help me Mr. Wizard I don't want to be a YANKEE anymore!!! Tudor Turtle!!!
Although not cartoons really, my favorites were Captain Scarlet (marionette type show) and Winky Dink! Boy did Winky Dink get me in big trouble. I didn't have the magic plastic thing that you were supposed to put on the TV screen to draw on, so I drew with markers (no such thing as Washable in those days) right on the TV! I was not allowed to watch that show for quite a few days "Winky Dink and you Winky Dink and me, always have a lot of fun together".
