I have a SUPER SEEEEEECRET CODE for you! I'm not telling you what it does! You have to try it yourself!
BEFORE the title screen comes up, smash your Nintendo 64 Paddle to peices, and attept to re-assemble it upside-down! Remember, if you don't do this before the title screen comes up, you have to throw away the parts and buy a new paddle! After completing that, do the exact same thing to all your paddles! Then, plug the upside-down paddles into the 64. When Mario's face comes up, distort his face until he looks just like Dr. Who! The first one. It has to be the first one. Wait for fourty days and fourty nights, leaving the game up, and Mario's face will stay that way! Mistaking Mario for Dr. Who, Toad will come up and ask Mario for his autograph. Don't give him it, or you have to start over! Toad will follow you around. Play the game until you get to Unagi the Eel, then feed Toad to Unagi! Mario will get so depressed that he killed Toad, he goes to sulk in the castle. Then, adjust the TV so Mario has a green tint. Walk him to the nearest body of water. He'll see his reflection and think he's Luigi! So, then beat the game. Princess Peach will say "Luigi! I thought Mario would save me! No cake for you!" and leave. Then, Tatanga will pull off his Bowser suit and capture Daisy! Adjust the TV so Mario's clothes are red again, go to Sarasaland, and beat Tatanga. Daisy will say "Mario! I thought Luigi would save me! No cake for you!" and leave. Then, Bowser will pull off his Tantanga suit and capture Peach. Repeat the color switch until you have gone through this exactly one million times WITHOUT SAVING, and Bowser will try to pull off his Tatanga suit, but he's not wearing a Tatanga suit! So he pulls off his skin and turns into a Dry Bones. Defeat Bowser Bones, and Eclair pops out! Then, Tatanga will appear and try to pull off his Bowser suit, but he's not wearing a Bowser suit! So he pulls off his skin. Defeat the Tatanga Skeleton, and Princess Pudding* will pop out! Now, Daisy, Peach, Pudding and Eclair have a giant catfight. Eventually three will be pushed into a lava pit, leaving one survivor! Run up to whoever survived, and if she's Peach, she'll be upset that Mario isn't here. If it's Daisy or Eclair, she'll be upset that Luigi isn't here. If it's Pudding, she'll be upset because she has a really stupid name. So the princess jumps into the lava, too. Mario follows them, but he dies. Instead of Game Over, Mario goes to the Overthere, where he meets ROB, Stanley, Mr. Balloon Fight, Mike Jones, and Pit. They get mad because they only had one or two games, and push him into the Underwhere. In the Underwhere, Mario meets Bowser, Tatanga, Wart, Smithy, Grodus, Count Bleck, Cackletta and Master Hand, who get mad at Mario for kicking their butts. They throw Mario into the air, where he blows up! Then, Shirguei Miamoto walks on screen and says "Look at you! You just killed Toad, Mario, and the princesses, all for following a fake cheat! And look at how much time you spent playing this game, GEEZER!" The game shuts off. Run to the mirror, and you'll see that you're old now! You then die of old age. Sucks to be you.
