The movie went on about 10 seconds too long.
Ok, so it's clear you're in your early days of making flas movies and I'm sure with time you'll get a lot better.
But this movie WAS funny, right up untill everything that occured after "bitch slap."
As soon as the bitch slap happened, it should have ended. Don't feel like you need to explain the joke, you'd have got more points for how random it was. As it stands, you took the only funny part and explained it - thus making it less funny.
If you're gonna have voices in their too, concider asking people you know to take over the voice of the guy that says "well for one..." and get a more proffesional sound out of them.
Keep working at it, you've got a way to go but everyone has to start somewhere! :)
