The Daily Show's John Oliver and some guy called Andy Zaltzman do a weekly podcast discussing current events and politics and stuff. It's hilarious, I suggest you subscribe to it. This week's episode has the first of six "Audio Tokens". Once you collect all six and send them in, they send an immigrant to stay in your house for a day.
