My own personal Nemesis

Here's a question: Anyone got any good ideas about how to vanquish a Nemesis?

I ask this because I have one, and unlike a basket of puppies you can't just dump it in the river and watch it float away. Or, better still, drown.

Things would be so much easier if I could just vapourise him, but I think the technology is still a few years off. Maybe banish him to the phantom zone?

Damn these pop-culture references! Answers on a postcard!!

(And the more they look like the Hooded Claw would've used them to eliminate Penelope Pitstop the better!)
