I thought that this was pretty funny.
However, the fact that you don't complete your cartoons is the main reason that prevents you from getting high scores. I bet if you looked up some books on anatomy, perspective, composition, color theory, and animation; you'll be on the path of being a Newgrounds legend. In other words, you have a lot of animation potential, but your tendency to lose motivation due to other artists who get high scores.
Art & Animation: while the characters were drawn with accuracy, and animated with skill; the fact that you didn't color it is what hurt the overall score. I bet if you went back and colored it all in, that will result in this getting a much higher score. Plus, I noticed that you do all your shading on a higher layer over the line art; an alternative to this is to use the flash color slider and turn down the value slider. It will look a whole lot better that way.
Sound: Nice use of the actual Team Fortress 2 soundbytes, along with the sounds from Maple Story and what not. However, you may want to get some voice actors because text-to-speech voices aren't going to help you in the long run.
Content: Unlike some narrow-minded tight asses, I don't have a problem with people using tv shows or video games as their subject material. And considering that you have a few original cartoons under your belt, you have some wriggle room to do so. Then there's the humor, which I thought was pretty good even though shit-related humor is overused. The execution and timing make up for that, and it's not often that you see sight gags used in flash movies.
What I did like:
-Good art and animation
-Clever use of soundbytes
What I didn't like:
-Not everyone likes text-to-speech voices.
Overall: Here's a seven out of ten, and I think you should save your cash for a drawing tablet.
