Well... It's a start
I didn't find it too funny. I guess I've just heard The Simpson's voices in so many videos that it's just not funny to me anymore. The part where Big Mario goes on a running rampage was pretty funny. But the graphics of everything breaking and dying were really choppy. When Luigi smashed his head on the brick, I was expecting some kind of HUGE over exaggerated head explosion with lot's of blood (yes I find that funny) but instead he cried. :( Also, work on the words that came up on the screen. I swear you wrote them with your eyes closed.
Keep on trucking man, you'll get the hang of it!
Was it just me or did the debris of Bowzer's castle look like a giant turd?
