In this episode, Martha (and then Stephen) are tortured by bad level design and user-hostile game mechanics in the original Japanese version of Super Mario Bros. 2, while Mark praises the oft-misunderstood American version of the game.

NOTE: Mark was wrong. There *were* mid-level checkpoints in the original Super Mario Bros.

Game: Super Mario Bros. 2 (Japan)

Mark really loves the American version of Super Mario Bros. 2, which you can read a lot about.
