When making small talk, ask for opinions farther down someone's list. Like, "What was the third best trip you ever took?" It catches people off guard in a good way, and garners better answers than asking for their top choice.

You can do it the other way, too. Saying, "that was the fourth funniest thing I have ever seen" immediately prompts questions from your audience. Just be ready with a good follow-up story if you try this.

Another option is to learn little party tricks that don't require much talking. Learn to fold simple origami, or some coin tricks, or whatever. When you're with a group of people and you don't know what to add to the conversation, you quietly do your thing until someone notices. Suddenly a banal moment becomes a memorable moment and you didn't have to say anything.
