The week of April 7 we re-broadcast our 2016 program with John Pollack, author of The Pun Also Rises: How the Humble Pun Revolutionized Language, Changed History, and Made Wordplay More Than Some Antics. It's fair to say that puns (and humor in general) loom large in our work here at Philosophy Talk, whether delivered off the cuff or to make deeper points about language and (mis)understanding. The Philosophers have also stepped back a handful of times to question their assumptions about what makes something funny, so we've pulled those episodes from the archive for some National Humor Month listening that might just leave you grinning.
