Wow - RTF makes sense - it's *supposed* to be opened by Word - but 
apparently Windows will check the file contents under certain 
circumstances.  I just renamed a Word file with a .yadayada extension, 
double clicked on it, and watched it open in Word.  It also picks up on 
renamed Excel files.  A few spot checks: negative on exe, pdf, html, and 
text files.  (This is with Win2k and Office 2k).

My suspicion is it has to do with the extra metadata you can attach to 
Office documents. (Right-click->Properties->Summary)
