Funny / Mario Tennis

  • Any time the Welcome Workout is mentioned in Power Tour. The player fainted during it and made quite a scene.
  • Starting up the N64 game without a controller plugged in leads to an image of Waluigi flying through the air holding the console while Luigi chases after him with a controller.
  • Power Tour also has Harry being too chicken to get on one of the Super Training machines, and then Kate hitting him with her butt, knocking over everyone in the line. Later, you can talk to Harry, who says that he finally got on.
    Harry: Thanks to the power of Kate's rear-end, I'm not afraid of spinning things anymore.
  • The GC game has Hilarious Outtakes of the intro cartoon after winning a tournament. Examples include:
    • Waluigi getting his leg stuck in a door.
    • Bowser pulling a lever, only to break it off.
    • Bowser pulling the same lever, only to get shocked and faint.
      Waluigi: Don't expect mouth-to-mouth!
    • Wario lifting barbells that seem heavier than he is, only to get a call on his cell phone. He continues to hold the barbells with one hand, while reminding his mother that he told her not to call him.
      • Waluigi shows up in front of the camera with an unamused look on his face and says "Cut!" in a deadpan tone of voice and places his hand on the camera lens.
    • Bowser trying to fire a Bullet Bill out of the cannon, only for the cannon to blow up in his face.
      • When he's actually able to fire a Bullet Bill, it misses Mario and just clatters on the ground without going off, and Mario just turns towards the camera laughing.
  • Some of the trophy celebrations in 64' and Power Tennis are amazingly hilarious:
    • Wario parades his trophy around and accidentally squashes it flat.
    • Bowser gets tricked by Peach into almost kissing a Birdo.
    • Yoshi mistakes his trophy for a fruit and accidentally swallows Luigi.
    • Shy Guy walks on stage to receive his trophy but trips and his mask falls off. Shy Guy gets up and puts his mask back on while Luigi sees Shy Guy's true face and is mildly freaked out.
    • In the 64 version, Yoshi eats his trophy and lays a golden egg.
  • Yoshi's defeat animation where he bonks his head in frustration until accidentally smacking himself in the back of the head the poor dinosaur ends collapsing on his side with a goofy look on his face
