Ever-sunny Nikki Boyer unmasked the Darth Vader Kid as Max Page, who among other things is a cute kid, was born with a congenital heart defect (he has a pacemaker), and has never seen Star Wars. Details here (you'll have to go to Monday's recap).
(And even if you're not interested in learning more about the Darth Vader Kid, at least you've gotta find Nikki Boyer compelling, right? No? Even if she's apparently no longer married to Roy from The Office? Still no? Man, tough crowd.)
