If you're crazy about public radio game shows (and who isn't?), prepare yourself for a double dose of NPR hosts. This week's Very Important Puzzler, Wait, Wait...Don't Tell Me! host Peter Sagal, gives you the inside scoop on his show's zaniest moments. Plus, shop for famous homes that were once featured in films and TV shows, put your knowledge of card games to use, and shake up a classic Beatles tune to shine the spotlight on animals other than "The Walrus."
