After a 17-month absence, AMC's Mad Men will be returning to television on March 25. Rock Center received a rare look behind the scenes of the hit show and learned a few secrets with Assistant Propmaster Johnny Youngblood.
Youngblood is responsible for each character's personal props such as Don Draper's watch, lighter, and cigarettes.
"[Don Draper] doesn't do anything without that. It's part of his character," Youngblood told NBC News.
