You have FAILED
Congratulations, you have FAILED!
Taking an overplayed sound clip and having an exploding head is not funny, as much as you might think it is.
The slight joke of it being a Howard Dean TV at the end had some redeeming qualities to it though. But your talents as an artist are impossible to judge by simply jamming a stupid picture of Howard Dean pointing.
The sound clip would have been ok with some custom animation. Try that next time around.
