Poor - even in humour.
Whatever way you look at this... this is animation of the lowest grade. I'm not sure whether you're making a calculated attempt to start a new fad or this is actually your sense of humour and this brings you amusement... either way: my genuine advice is to note down a couple of ideas for an animation; consult an adult or someone who's opinion you respect and use the idea that appeals to them the most; the other ideas you can tear off from whatever paper you've scribbled them on and line a pet rodent's cage with them. The idea that you're left with can STILL be improved upon I'm sure... work at it. Hopefully some originality of characters and situation can come from redrafts or reworkings of your initial idea. The cut and paste style you've got going on is tiresome, watch some of your favourite animations and see what kind of movements seem to fit characters more, try and give life to you're characters instead of merely have them slide statically from one end of the screen to the other. Hopefully, if you actually have some passion for animation you can create a piece of worth and redeem yourself to anyone that has witnessed this lame animation, doubtful as it is that the foul taste will leave anyone's mouth... that's bile, by the way.
If you've read this, I'm pleased; I hope you can think about what you've done and feel a little bit of shame for the low quality of your animation... not only have you (allegedly) wasted 3 weeks of your time... but you've wasted a couple of minutes of mine. I didn't have to watch, sure, I didn't have to leave a review either: but I thought I'd do you a favour and lay it out clearly. Best of the luck in the future, for the sake of your time as well as everyone else on newgrounds.
Peace
