Q: How do I find my iPod's serial number if it's been stolen?

My iPod video was stolen two weeks ago, and the police told me that, if they somehow recover my iPod, it'll make it much easier for them to return it to me if they have the serial number. Unfortunately, I've had the iPod for several years so I don't have the original packaging or the receipt anymore, nor is the iPod registered in my Support Profile. I know that, if I had it, I could hook it up to my computer and the serial number would show up in iTunes, but I obviously can't do that. However, I have obviously hooked the iPod up to my iTunes before, so I was wondering if there was any way to go back into my iTunes history and retrieve the serial number that way somehow. Any ideas?
