Has potential.
Few things to make it better. One, every time someone says a line, theres a short 2 second pause before the next line is spoken. Two, most of the characters sound the same, and are kind of nonchalant, which makes the jokes lame and boring. In actuality, they are kind of funny, but you didn't deliver it well. Im assuming you voice act all of the characters ; try getting different people for the different characters. The animation? It fit the cartoon, so thats a plus.
One sentence synonpsis, More energy! Accomplished with varied voice actors to fit the distinctly varied characters, and quicker timing.
P.S. You had the idea of having a duck in the cartoon, which can strike as odd since he bears no relationship to the other characters. Use it to your advantage, make it a lovable character. (Snoopy was the best character in Peanuts, yet he never said a word!)
