One test was to see if you can laugh at their laughs, in real-time standing comedian talk shows. like this:
Her ability to interact with the crowd spontaneously... it's a rare talent. :-) if you're the one in that crowd and got picked-up to speak out ! "Every show is different and she never misses a beat. "
"Starting at 35:50 is a prime example of why audience members should never challenge what a comedian says and just play along. Paula takes the time to create an entire caricature to dismantle the confused man who thought her question wasn't good."
Paula Poundstone - Look What The Cat Dragged In 2006 standup
Paula shows up on Wait Wait Don't Tell Me wearing a Pilgram's outfit. When asked why she was wearing it she replied 'I read this article or book on how to declutter your life and it said 'if you haven't worn a piece of clothing for over a year, throw it out.' Take from there. Her logic is impeccable and how she winds it into her comedy is true artistry.
