Will and Mango are determined to figure out the origin of the emergency hotline. From the strange reason people used to call up funeral home directors after an accident, to the incredible train robbery that was stopped using a makeshift phone, to the heartbreaking ways that emergency operators learn to cope on the job, this week we're dialing up a whole host of 911 facts.   ... Want to get in touch? Whether you want to share a fact, story, or even just let us know how we're doing, you can write our moms (Lalita and Paulette) at PTGeniusMoms@gmail.com. Don't worry. They'll pass the message along.See omnystudio.com/listener for privacy information.
