Action Adventure World created a rap for Nintendo's Super Mario Land that's so cheesy, you have to listen to it:
Here's my favorite verse:
It's the goomba stompin mushroom poppin
Koopa Clompin Body dropping
Fireball in my hand
Run and jump duck and slide
To get the box on the other side
Braking bricks with my f****n fist
B***h I'm coming inside
Through the castle no hassle on my way to the end
Daisy went and got kidnapped again
It isn't Koopa but they might be friends....
I'm gonna whomp you motherf****r don't even pretend
