Nice animation
I have heard this song before and it was funny to see it in flash form. I think it's kind of cool how it turns out that wasn't really Santa Claus in the first place. The animation is probably this cartoon's strongest point, especially with how the snow is drawn. I guess he thought the Santa guy was a burglar, but he shouldn't have shot him so many times. It had an unexpected ending as mentioned before, although you didn't make it. I am quite impressed the animation was done so quickly.
