Use a very powerful magnet and a pair of pliers. Have something hold the iPod upright with a magnet in one hand and pliers in the other. Get the magnet to pull it out partway then grab it with the pliers. If that doesn't fix it, use ifixit's teardown to get the back case off. Once it's off, there should be an opening at the back of the headphone jack you can put a toothpick through. Put a toothpick in the hole and push it out. Hope this helps!
