Quick hands and one of them with a rag in it.
I always put the drain pan underneath it when I pop the filter off to catch that little bit and then have a rag already sitting there waiting to catch the spillage.
Don't worry it'll burn off in a few seconds. Just like the plastic from my distributor cap that I changed the other day and just remembered that it fell down under the engine. Found it last night when I was changing a motor mount. Oooooops, a little plastic melted on the exhaust never hurt anyone.
