The Story Lady: My previous pastor put me on to this incredible repository of old radio shows and shorts, which can be downloaded as podcasts, if you want to listen to the Detroit Tigers play the NY Yankees in 1934, for example, while you power walk.
The Story Lady is 1 minute shorts, similar to the Fractured Fairy Tales of the Bullwinkle era. I recommend "Rumplestilskin." And then "The Frog and the Grilled Cheese Sandwich."
Plenty else: Grantland Rice, PG Wodehouse, A Canticle For Liebowitz, the Aunt Jemima Show, the Goon Show. You could get lost here.
