We begin with a couple of silly people – comedians Kristen Schaal and Kurt Braunohler (of the Hot Tub comedy series) – deciding to do something silly. And at first, it’s very funny. Then they do it again. And again. And again. Until... it’s not really very funny anymore. Until it is again. Jesse Thorn, host of the radio show The Sound of Young America, explains.
 
Next we meet Christine Campbell, who one day discovers her mom, Mary Sue, is trapped in a mysterious (and rather terrifying) loop within her own mind. The condition leaves Mary Sue’s doctor, Jonathan Vlahos, pondering just how much control we have over our own actions.
