To listen to this podcast, you must solve a riddle: What goes on four feet in the morning, two feet at noon, and three feet in the evening? Stumped? The answer is that it is a dog who, just before 12pm, decides to pretend to be a human so that it can buy cigarettes. Later that day, it hardens one of the cigarettes with wax, and uses it as a crutch because its hind legs are so sore. Anyway, I've been the Sphinx, you've been great!
