In Game Stores, Scott is talking about the GameStop generic cases and how they look unappealing. However, he does mention that the GameStop case for Mario Tennis: Ultra Smash is better than the actual game. In Wii Play - Eh, Why Not, Scott mentions how Chibi-Robo! Zip Lash, Mario Tennis: Ultra Smash and catching a Small Fry in Wii Play fishing were the biggest f-you's Nintendo has given him.

After Scott goes to Jerry Attrick's house, he says that he needs more therapy after playing Mario Tennis: Ultra Smash, and they start their session despite Attricks not being a certified therapist. Scott mentions how he didn't buy the game at first because he thought the game was lacking in content and didn't look much different than the first time it was shown in a Nintendo Direct. Wozniak also didn't buy it because of Animal Crossing: Amiibo Festival, which was also lacking in content and released only a few weeks before. However, he ended up buying the game for $20 a few years later. When he tries playing the game, he realizes that he should play it with some friends, so he invites Rex Mohs and Jeb Jab to come over. They go through all the modes as Mohs slowly loses his patience for the lack of Mega Battle as they play them.
