Hello, I'm Greg Jenna and good news, Your Dead to Me is back for a new series. Here we go. Yes, we'll explore Emperor Nero's notorious reign with Professor Marybeard and Patton Oswald. I would not want my daughter having the remote control, not alone an empire. We'll dissect the decadent life of Philippe Duke-Dor-Leon with Tom Allen.
