Description from the publisher:
Are you such an expert pitchman that you can sell ice (that attracts beautiful butterflies all summer long) to Eskimos? Then the But Wait, There's More!: That's The Best Part! expansion for you! Every good pitchman lets his audience ask questions, and that's precisely what this expansion adds!
After each pitch, the next player plays their "That's the Best Part!" card, which contains a curious question such as "What happens if Grandma can't lift it?" or "What happens if it induces vomiting?". The pitching player responds with a confident "That's the Best Part!" and has to continue their pitch, quickly improvising an answer!
This add-on expansion contains forty new cards and brings a wonderfully entertaining new aspect to But Wait, There's More!
