This was good, don't follow suit to the negatives.
All the reviews this flash was getting was really going out of hand, a handful of zeros just because you didn't think it was appropriate?
Oh yes, you may think this may be just childish humor but that's just that, just the "in-your-face" humor the creator intended to be.
I thought the overall flash was hilarious, I see how you portrayed how much you disliked Lisa due to her face (which, I can't help but laugh).
The animation seems to go really well, although it seems you traced almost everything, I'll let this go since the humor backed up the flash a bit more.
It's nice to see the background is still intact, I'm very glad that you didn't make any quick changes to it.
The characters I liked the most is Homer, just because of the ending you gave him, lots of laughs there for sure.
Again, about the humor, not to say that it's bad or anything, but it's beyond "childish" level.
The word "rape" is used a lot usually to make a cheap laugh, and it sure did give me a cheap laugh.
But I know already, this wasn't serious at all, by reading you're description of course.
Overall, this flash had potential to be good, the length was good and the drawings/animations were to be desired (making it your own style, etc...) but it was good.
So, this deserves the score.
