It must be a sign of the times or in Roger Sterling's case, just another resplendent mustache. Mad Men creator Matthew Weiner opens up about all the facial hair his characters have been sporting on the show, which have so far both shocked and appalled viewers.

According to Yahoo! Beauty on Friday, he said, "Well, we've toyed with Roger's mustache a couple of times, but we had to wait until there was a mustache that looked good on him. John Slattery doesn't look good with a white, trimmed mustache-it's just too Larry Tate. This soup-strainer thing that's going on is much more appropriate for him. And I just felt that Ted, who's newly single with a bachelor pad, will do everything he can to appear hip."

Weiner also added, "Someday, someone will be looking at the pictures from 2015 and laughing at all the beards. The insanity! I'm talking about spectacular, hillbilly, hipster beards-and even your obstetrician might have one."

Meanwhile, Jon Hamm, who plays Don Draper on the show, has opened up about the role and how he's struggled playing the iconic television character at times.

According to the Sydney Morning Herald, Hamm, who plays the show's protagonist Don Draper, says that playing the womanizing advertising genius hasn't been easy for him.

He said, "Acting is not a physically demanding job, like playing professional football, or breaking big rocks into little rocks, but it does take a lot of focus and mental acuity, and it takes an emotional toll. Especially when you're playing a person with a lot of emotions; you can have a lot of sad days at work."
