Very good story and plot. Humorous and unexpected!
The voice acting stood out as very strong and maintained a tone that kept the plot twist hidden well. Very, very funny and my only advice would be that you should increase the length of your submissions and develop the plot better; however, the short, lack of animation from the first scene served as an excellent juxtaposition for the ending violence.
All in all, an above average submission and your voice talents makes me hopeful that you will produce more going forward!
