Stephen Colbert is a multi-talented comedian who worked with Jon Stewart on The Daily Show then had his on show on Comedy Central before moving to host a late night talk show. That up until early 2020 was taped in front of a live audience. Enter COVID-19. Everything is paced differently now with these talking heads working from home. For the same reason the Oprah interview was conducted out of doors under the pergola of a property belonging to a mutual friend of both women. So much is being done outside or very well-spaced.

I agree, "muggle" is a good term to use here. :)
