9. 'Professor Blastoff'
Beyond its crew's insistence that Professor Blastoff is a science podcast, the show explores any subject that implies expertise — including recent dips into the realms of the Tarot and midwifery. Beyond a recurring gag featuring the computerized voice of "the professor," the formula is simple enough: Kyle Dunnigan and Tig Notaro bounce bits and characters back and forth while David Huntsberger does his best to keep the guest interviews on track. Listeners can engage as they see fit, either listening closely to learn something from the subject at hand or simply floating along as Tig and Kyle goad one another to ever-sillier asides.
