If there is one thing that you need to know about Ira Glass, aside from the fact that his voice has the texture of fine silk, it’s that he swears a lot in person. That’s according to Mike Birbiglia, who worked with Glass on Don’t Think Twice and had to suffer through the experience of getting notes from him in a Power Rangers–sized video conference. Point being, Ira Glass is everyone’s favorite hip creative-writing teacher, if that creative-writing teacher used language that would embarrass a 19th-century sea captain.
