Definately needs some improvement.
There weren't too many thing to smile at in this flash. I thought the ending was pretty clever, but that's about it. I don't know if you did intend the animation and drawings to look that way, but it would really benefit you if you added quality animation to it instead of just pictures and motion tweening.
The story also didn't seem to have a real plot to it. Mike gets a television and then his house explodes. It doesn't really advance the plot and I didn't get a laugh out of it. Simply put, a storyline is vital to flash success, this just needed more effort. Also, try to get someone to do some voice acting, that will surely benefit you.
I can tell you have some creativity inside of you, now use it to your advantage. I know it's easier to leave effort out of a flash, hell, even I lack effort on my flashes, but this wasn't that bad of a flash, I've definately seen worse. Stick with the basics and you should gain flash skill. Keep up the good work!
