There's a method, gents. Push the gooch a few times while using your "stop peeing" muscle. Then, pinch the shaft, applying pressure from the underside. Starting from the base, bring your fingers forward up the shaft towards the tip until you get those last few drops. It's clumsy at first, but you build a routine and the drip drip is a thing of the past.
Women who try this: you're just going to end up with your fingers in your vajayjay, not that I discourage that.
