Incredibly Funny!
I had to watch this a few times just to get my fill. It seemed like an innocent enough video during the first few seconds, but by the time Bambi was born, the opposite was apparent. I loved the dry humour employed, and the animation was fluid and consistent. My favourite part - where bambi started glowing to the megaman sound effect and flew to the superman music with rainbows coming out of his ass - was beautifully done with such brutal and honest humour when the other deer said to him, "Bambi, I didn't know you could fly." (and with hardly any expression on his facae, too!).
All in all, very well done and definitely going on my favourites list. As a side point too, I like that you did the compositing in AE and went with a video format, because if it had been vector animated my computer (and many others, I'm sure) would likely have struggled to play it smoothly.
