Not bad
Though your drawings and animation are pretty good, but there are some flaws with the presentation, overall. For starters, the flash as a whole just moved too slow for my taste. With a funny flash like this, sometimes it has a better effect when the punchline is delivered quickly.
Also, the lip syncing was quite bad. I know you mentioned it in the author comments, but it is something I would address, if I were you.
Overall, this has some pretty sweet potential to be a great series, if you're willing to put some more work into it. Keep it up!
