"Mad Men" star Jon Hamm returns to "Saturday Night Live" on Saturday, Jan. 30.
Hamm, who cut these two teaser promos with his co-star Elisabeth Moss' husband Fred Armisen, actually startles us at the end there.
Hamm recently appeared with a beard at the Screen Actors Guild Awards, where "Mad Men" won for best ensemble in a drama series. It seems he shaved for "SNL," but depending on his hair growth rate, he could look different once Saturday rolls around. He does, after all, have many faces.
