It first appeared in the episode Million Dollar Maybe where Lisa purchased one in a hardware store for the Springfield Retirement Castle after observing Mr. Burns playing two games on the console, one called "Zii Sports" and another unnamed game that takes place in World War II. Lisa then took the Zii back to the retirement castle and sets it up for Grampa and the other residents, who were confused by the technology at first, but soon warmed up to a game of virtual tennis. The residents eventually began to feel younger and start bossing around the nurses, who in response destroyed the Zii by putting it in a dishwasher. It also appears on The Squirt And The Whale . Lisa and Bart are playing Zii Sports and then Bart punches Lisa with the controller and then they fight.
