What file extension are you?

I came across yet another one useless and irrelevant quiz. It asks you about 20 questions and by the answers provided it determines which file extension reflects your personality in the best way. Take it – it is fun. My result is SWF (which is the file extension of Macromedia Flash files). The description of the result is:

You are .swf. You are flashy, but lack substance. You like playing, but often you are annoying. Grow up.

The two questions I have now are: am I happy with the result and should I beleive the results. :)
