This week, we’re bringing you an extra-special episode from our friends at the podcast “But Why”:

Why do we laugh? Why do you feel ticklish when someone tickles you? Why can't you tickle yourself? We learn about how humor develops with Gina Mireault of the Infant Laughter Project at Northern Vermont University. Also in the episode we hear about April 1 traditions and we listen in to jokes from our listeners with Vermont comedian Josie Leavitt.
