Welcome back to “Inconceivable!”, the show that tests two teams’ knowledge of the nerdy, the useless, and the obscure. By your powers combined, this episode’s panelists take on a spate of trivia about the classic ’90s cartoon Captain Planet and the Planeteers, play a rousing round of What’s the Difference?, and manage to decipher a host of characters who are stranger (in fiction). Frank Wu, Lisa Schmeiser, and Steve Lutz take on Marisa McClellan, Scott McNulty, and Erika Ensign in a battle that will shake the ages, while Dan Moren and scorekeeper Lex Friedman try to keep a semblance of order.
