Wow, this is a big one...
Play as Mama-Luigi:
Find any N64 Carridge ( I'd recommend it NOT be SM64 because that's what the cheat is for... ) and do your Final Smash on the top half of the side with the label. Now, you should see Hotel Mario floating in the air saying,
"Go to the TMK staff page. Oh, and would you like a handy instruction book?" Ignore the HIB ( Handy Instruction Book) and go to the TMK staff page like he said. When you get there, scroll down to Chupperson Weird and his head will magically fly out of your monitor,( Mac compatible, OSX10.0.4 or higher! ) into your bedroom, and on your bed. This is the fun part. Take out SM64, and Chuppersons arms appear out of no where! Now put SM64 in the N64, turn it on, give Chup the controller, and he'll start playing! After 8 Hours, ( he might have beaten the game hours ago and just started running and jumping randomly ) take the carridge out, and Chup will start swearing horrible things and explode. The smoke will read 'Congrats! You destroyed Chup!' Now, put Super Smash Brothers in and start playing. Unlock Luigi, and K.O. Mario exactly 7,021,945,378,514,215,884,635,626,984 times. You should see your SM64 carridge start glowing. If so, immediately turn off the N64, and take SSB out. Quickly now! SM64 will do three loops in the air, dive-bomb your bed, land in the N64, and turn on. Get a very high-tech timer, and wait 452.541354351243663131253654165464489798416549879651164 seconds.
The world will go to another dimension, and look for Mama-Luigi ( who is actually Sam Snead in the other dimension... ). Convince him to go with you to the other dimension. Get him to hit a golf ball to rip through the sound barrier, and open the gateway between dimensions. Go through and it will close. The golf-ball came to, and hit your N64! At mach 9! Don't worry. N64 have a ' Anything Above Mach 3 ' force field. Anything at mach 9 opens a portal and sucks anyone in randomly. If it's Sam Snead, "Way To Go!" If it's you, you won't be reading this.
Anyway, Sam Snead will be mutated into, you guessed it! Mama-Luigi! Now you can play as Mama-Luigi!
There, that wasn't so hard, was it?
