They're drawing chores while Marge is in the hospital from stress.
Unfortunately for Lisa, all of Homer's draws are practices. Homer and Bart end up at a leper colony, on Flanders dime.
Is that the hat Marge wore in the episode where she becomes a real estate agent and Homer buys Lil' Bandit?


Duotron!
It's not really a highly regarded game, but my brother's first game was a Magnatron (same game, just 4 players instead of 2), and this came up as a restoration project, so I've been working on it. I swear the engineers were making music with the reset sequence. I'm sure it's all necessary, but there's a catchy element to the sounds it makes, too. It's my first restoration project, so probably good to start on a game that isn't super valuable.
I've got it in pretty good shape, sort of. The playfield is pretty worn, but it's clean and waxed. It plays pretty well, I need to clean the contacts on the bonus wheel and just play a bunch of games to make sure the score reels are working. Definitely one of those things where the more I play, the better it works. I'm planning to take it to a show in May. I need a few random parts like locks for the cabinet doors, but it's basically ready to go.
I also have my brother's Loop the Loop sitting there, and it plays fine, but it's covered with Duotron parts and schematics. I also have a RollerGames and a Bobby Orr Power Play in the house.
