nice theme!
I love the "roadrunner" style cartoon. Slapstick is just awesome. Too bad this wasn't a longer movie.
In regards to your comment about the file size I think I can guess why your file size is so big, and it's probably got to do with your sound clip(s) and or bitmaps. So I'm going to offer hopefully some helpful advice, and if you've tried this already then please pardon this. If you go into your flash library window and select the sound clip and right click it and click on "export settings" you can export as MP3. Try exporting as MP3 with maybe 8 kbps and that should hopefully cut down your file size a bit. Also trace bitmaps and save as movie clips and use the movie clips in the frames vs. bitmaps. That helps too. Just some tips that I know could probably easily cut down your file size for this. (I did not know about the MP3 setting myself until someone else had pointed this out to me and that really helped me a ton).
The grenade rolling around and hitting Bush was a riot. Though I'm not big on Bush bashing personally I still can appreciate the comedy aspect and in my opinion you can't really go wrong with the "roadrunner" theme. It's one of my favorites! Keep up the good work!
