Non stop chatter

I recently attended a large dinner event. The person next to me didn't stop talking to me all evening. How can I get out of situations like these?

So you're trapped at a sit-down dinner, next to someone who's apparently trying to set a world record for continuous talking. You want to mingle, network, maybe even enjoy your meal, but you're caught in a one-sided conversation. Here's how you can handle it with a bit of clever manoeuvring.
