For starters there would be a half hour long cut scene intro, followed by 20 minutes of endlessly respawning pink bunnies, attacking by farting at you. When 20 minutes have passed, I come out with a gigantic axe. Because of the size of the axe, I'm slow, and whenver I swing it, which I am never NOT doing, it gets stuck at any and all scenery, including the walls and floor. You can only beat me by throwing stones at me, making me a tediously slow, but ridiculously easy boss.
At 1% hp, I evade bug into a wall and the text "tough shit, *****" flashes on the screen... in flourescent pink.
And then you have to do it all over again. And again... and again... until you realize that the only way to beat me is to turn off the game.
