YELLING IS NOT A JOKE.
Does it get the viewer's attention? Yes.
Is it funny? No, it's just obnoxious.
Besides that, there were one or two jokes that were pretty funny (the blood jokes and the can jokes), but the rest of the jokes didn't make much sense. Next time I would structure it around one bit, like the segment where one of you threaten to bite your arm off. It could use some more structure.
I have to give props to your animation though, it's really smooth. It is definitely my favorite thing about this cartoon.
