Well
I usually read authors comment before i watch a flash, so i understand your motives behind this, and i shall offer you some critisism cause you asked for it so nicely.
First off, as you already stated, sound and animation is not that great, and i understand why you dont want to focus to much on that, you wanna be a comedy writer, but here in lies the problem. The pasing, voice acting, and animation took out the edge from alot of the jokes. It became sluggish, and at times well, kinda boring. I found it hard to keep my focus up long enough to catch the jokes hidden inbetween the fillers and stuff.
And sure i think dick jokes and the likes are fun stuff, but when everything starts revolving around it (spewing, tits, dicks and gay jokes) it starts to get a bit old.
Have you thought about trying to find a animator along with some voice actors to write for? You said you wanted to be a writer, and whats better practise then trying to work with some people over the net? Not only do you gain the experience at working as a team, you also gain feedback, and a hopefully higher quality overall.
All in all i found it a decent flash, but the sloppy animation and sound sorta took lots of the edge of for me.
And for the record, one of the points of being in comedy buisness is trying to be either original, or surprise people. ThreeD did offer you some serious critism only in a very sloppy way. You want to improve, then dont flip of your audience, even if their views on things are in direct contrast to yours.
Thanks.
