When Homer was trying to get candy out of a machine in the Nuclear Power Plant, 8-Bit Homer came through. 8-Bit Homer and the other Homers who came through then went around Springfield together, eating, bowling and causing trouble. In order to get them all home safe, Marge opened a beer, causing them all to come rushing to her.
The Homers found out that they all have to go home to their universes or they will die, so they went to the Power Plant and attempted to recreate the way they got there. Mr. Burns tried to stop them as the device is a way for him to get cheap, undocumented labor. A group of alternate Mr. Burns' then appeared to fight the Homer group, with 8-Bit Homer fighting against a Bowser Burns. When Burns found out that in the Noir universe, Smithers was his boss, Burns sent all the alternate people back to their universes.
