Mr. Olson appeared in the episode "The Tale of the Pinball Wizard". He was portrayed by A.J. Henderson.
He is the evil owner of an electronic fix-it-shop at a shopping mall. Previously he had to fire his old employee Steven. Then he ends reluctantly giving Ross Campbell a chance to watch the shop for him late one afternoon when he goes out to lunch. On his way out he specifically told him not touch his new pinball machine game. Ross gave him his word that he could trust him. But as soon left, Ross broke his promise and begun playing the new pinball game. He knew, because he could overhear him playing it on his way out.
When Ross played his new pinball game, it transported him into the fictional world of the plot of the pinball game. Which was a medieval game where the player had to find a throne and a tiara and crown the princess, before an evil witch, or an evil sheriff could crown either of themselves. Ross played the game out and won, thinking he would be freed at the end.
Later on when Ross wins the game he ends up trapping him inside the pinball machine as punishment for breaking his trust. How he is able to do this is completely unexplained Some possible theories could be that, either he is a secretly a warlock or a slightly magical person who creates pinball machines as evil containment units and decides who to put into them. Then he starts a new game, which showed him about to send a huge silver pinball crashing into Ross. Ross had the hunch that now he would never get out!
