Canon 50mm f/1.8 Problem at DVinfo.net

Ok, first of all I apologize if this isn't the best place to put this, but I didn't see a "lens discussion" forum, so here I am.

I have the Canon 50mm f/1.8 lens, and it appears to have a small piece of plastic on the inside of the glass. Its actually not a problem, until I start messing around with taking out of focus shots on very bright things (so a nice fade out of focus or into focus with Christmas lights). With those out of focus shots, you can CLEARLY see the piece of plastic in every bokeh circle.

I have banged the lens gently on my hands, and blown into it to try to dislodge the piece, to no avail. Has anyone else has a similar problem? Is there a way to shake the thing loose, or a proper way to dismantle this lens to get it out of there?
