New fluorescent light rattles, should I worry?

I just received a 65W PC bulb in the mail. When I tipped it from side to side, I could hear something rattling inside. I plugged the bulb in, and it works just fine. Is this something I should worry about? Should I exchange it?

Not a problem at all as long as it doesn't damage the filament inside the bulb. At least half of the CF bulbs that I have owned have rattled.

I just posted this question myself a few weeks ago! It was strange to hear what sounded like some object moving in the tube, but mine lighted fine too and everyone said that sound was normal.
