Michael Ian Black is known for his deadpan, sarcastic comedy, but in his podcast and new memoir, he’s surprisingly earnest. Also, we’ll hear about what may be the worst film ever made, “The Day the Clown Cried,” from 1972. Only a handful of people have seen it, but now that its director and star Jerry Lewis has donated it to the Library of Congress, more of us will one day watch it in all its glory. And we’ll hear the 1920s recording that set the standard for traditional Irish music ever since.
