Not bad! :P
In terms of writing and pacing I'd say things were pretty good, although I think there could still be some more frames of animation added to the cartoon.
When it's the 'smashing' party, people are moving around and hand gestures are being made. With the 'smash' party, movement is limited to just one character just moving his thumb. While the joke was meant to show that not all that much was happening, you could add some simple shoulder/hand movements from the players as well as some blinking. Just adds to the animational merit and overall quality of the cartoon.
Just something to keep in mind, but I enjoyed the cartoon regardless.
Keep it up! :)
