We're all seeing double this week now that we've made it to our 222nd episode. We don our raccoonnookkeeper uniforms for Chris' double letter Scrabble word challenge but this time, it's all about words that strangely begin with twinning letters. Celebrate human-animal pals in this Dana's duo quiz, and learn weird facts about reduplicated cities that are so nice, they named them twice: Walla Walla, Pago Pago, and what exactly is so funny about Canada's Saint-Louis-du-Ha!-Ha!? Buy low and sell high in Colin's corporate partnership quiz with some mind-melting trivia behind famous companies. And of course, we're traveling to our third destination in space trying to catch Carmin San Mateo and her greaser henchwoman, Didi Connvict.
