Not bad, but...
Ok, this wasn't a bad flash. The artwork was a little spotty, and could use some work. The voices weren't too bad, though.
The real problem I have is that the humor was uneven. I laughed a few times, but just as often found myself rolling my eyes at the jokes. There's a fine line between comedy and cheese, and it was crossed way too often here.
Here's my comedic two cents. Most flash animations on this site aren't really long: 3-5 minutes on average. Instead of trying to cram a lot of jokes into the limited time, work on developing just a few good ones, say four or five. The result will be much more developed comedy instead of comedy that bounces all over the place.
