When I used Facebook's Open Graph API, I noticed that the JSONP responses generated by Facebook seemed to have an extraneous "/**/" at the beginning of each response like this:

URL: 
https://graph.facebook.com/SOME_ID?method=get&pretty=0&sdk=joey&callback=FB.__globalCallbacks.f1c77f051c

Response:
/**/ FB.__globalCallbacks.f887adeec(...);

Why is this?
