Very funny, man. You got a few laughs outta me.

However, this doesn't mean that there is nothing to improve on.
Try to make things less copy paste, like the background for example.

Also, try to make your characters more lively, when they're moving in the truck try not to move them slightly to the side, it looks like you just selected your character and rotated him more to the right when he moves.

But aside from that, shit was funny man!

It was eh, I wouldn't say a huge waste of time, but I can say that I know the author tried. The animation is good, I just couldn't get into it seeing really no plot to it.
