Long before he portrayed a hitman turned aspiring actor on Barry, Bill Hader gifted us the giddy city correspondent Stefon, accompanying Seth Meyers on "Weekend Update." Between Hader's fake tattoo sleeve, lowered voice, and constant breaking, there's so much to love about this character. The Halloween bit is especially hilarious, and we get to see Hader erupting into giggles after saying, "This place is going to have everything: ghosts, ghouls, goblins . . . my son."
