Dr. Floyd and his nemesis Dr. Steve

Yes, you can learn about these two characters and many more by listening to the episodic SF podcast called The Radio Adventures of Dr. Floyd. It is a series of 4 to 6 minute episodes done in that “old time radio” style (as per their webpage.) I have listened to the first two seasons and these guys have a formula that works. Its family friendly and educational too – plus its darned funny. If you have not really listened to a podcast, this would be a great one to start with.
