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! :)

Hey, nice job! It was quick, funny, and not dragged out! As for constructive criticism, maybe for your next flash, you could improve your color pallet, with shading and what not. There's also some instances of perspective issues, such as at 0:19, there are two hammers, but they're not following any perspective rules.
Also, just wanted to note, this cartoon really shines in the writing, and I'm glad this joke was based off an observation because comedy seems to be funnier when it's based on observations that the writer makes.

Bottom line, great job! This was a very funny cartoon!

Everyone calm down, this is just a joke about melee elitists.
