I felt pretty much annoyed about 15 seconds into the movie. Don't get me wrong, the graphics were very well done, kudos to you, however, the entire flash was pretty much the same mediocre joke. Don't take this the wrong way, but you may want to consider having someone help you write a script for your next attempt. From what I can see, most of your animations have an obvious plot with hand-fed motives and emotions. Your animations lack subtelty and feeling, aside from that, once again, I must stress that you have a nack for graphics and the actual animation aspect of the cartoons. Even for a short, silly animation, which most of yours tend to be, there needs to be more luster in the storyline, if you could call it that. You spend so much effort on the animation, but all you need is a solid story with originality and subtelty.
Nice job overall, I still like the 'your mom' part,
