He did have some odd attributes.
He always talked in deadpan monotonous tone. He also walked without swinging his arms. I will say some of the episodes were very very good.
I remember one where this kid worshiped some comic book super hero. He had a big picture of his hero on the wall. When Friday caught him the kid started to weep. He went up to his hero poster and placed his face against it. when he moved away, the poster had tears in it’s eyes.
Oh, that episode with the crying kid and the superhero poster? The actor went on to play Chet in Emergency.
BTW, the scene looked cool, with the tears coming out of the poster's eyes, but unless "Chet" had a totally flat face, his tears wouldn't have been so "neatly" placed on the wall. They'd be smeared on the cheeks.
