From the official site's biography:

“The Boston Globe says “she’s never been funnier.” Appearing on stage with a stool, a microphone, and a can of Diet Pepsi, Paula Poundstone is delighting crowds around the country on her hilarious national tour. There’s a wonderful synergy to each one-of-a-kind two-hour show. Paula’s ability to create humor on the spot is legendary and with her casual air, impeccable timing and razor-sharp wit, she improvises with a crowd like a jazz musician. She’ll find an audience member who sells grass seed to golf courses in part of the state of Maryland and wonder aloud if, in such a small territory, the grass seed were any good at all, the salesman could possibly be working to his full potential, then swing in another unexpected direction without a plan, without a net. Poundstone is so quick and unassuming that audience members leave complaining that their cheeks hurt from laughter and debating whether the random people she talked to were “plants.”
