Please speak up
This was not good because I could simply not understand what anybody was trying to say. I guess it was nice to hear that music at the end but overall it was quite unsatisfying. You should have also put a background in. You can change the volume of the microphone on the computer. It is too bad you won Turd Of The Week award, but you can take this as learning a lesson. I can see something like this happening in real life, not that I could understand it.
The lips synch up well, but it is hard to understand what is being said, again. I guess it probably would have been funnier if I could understand it. It was quite random to just freeze the characters at the end and play a song. Your next submission should probably be longer. You might also want to work with grammar on your title.
