A good start.
This was pretty impressive for your first flash. I'm a big Mighty Boosh fan so I was entertained by the sound bite, it was just as funny here as it was on the television. The lip sync was delayed at times which got to be pretty annoying, but the movement went together with the audio pretty well. The mallet hitting the table sounded louder than most of the other sounds which didn't really seeem fitting.
You might want to add a preloader just to be safe. It may not be necessary for a small file like yours, but it still makes the flash look a lot nicer and less cluttered. Good job on this for the most part, it was nice to hear some audio from my favorite show mixed with one of the best games to play. I'll recommend your flash to the Phoenix Wrong collection too. Keep up the good work!
