It was alright
I can see you really put in time and effort into this project. I like the story, even if it was a bit silly. I think that the audience for this flash would be around 11-13 years old though. The silly jokes worked for awhile, but it got so dragged out in the middle.
The exaggerated lip sync was the most funny part of this. But there's a problem there though. The bodies are not as interesting. Take Ren & Stimpy for an example; They use the body language as much as they go by facial expression. You should do that too and it would look a lot better. You should try it sometime at least.
You should also talk with the voice actors for the next creation. Because the voices were a bit gloomy. A good example of that is when the phone "screams" at the others but it comes out more as a whisper. The voices must have more emotion to be interesting.
Yet, you should get a big credit for the storyline. It's like something you'd see on CN. Myself, I usually have big problems with coming up with ideas like this one. So good job on that.
Hope to see even better things in the future, I'm not going to miss it.
