Is it outside? You'll want it outside. You'll also want a face mask or something to keep your boogers their normal color. Make sure there's nothing close by that will be damaged by heat, then melt that sucker out with a propane (MAPP is faster, but more $$$) torch. It will take a couple minutes of heating before it starts to melt/drip/burn/smoke out of there, but it will work and you'll just have to clean the soot off when you're done.
