Kristen Wiig On 'Portlandia': Crazed Stalker Kidnaps Fred And Carrie (VIDEO)

Kristen Wiig -- sorry, Oscar nominee Kristen Wiig -- visits "Portlandia" in this week's episode, playing exactly the type of character she naturally would inhabit in the Portlandia universe: A crazed stalker obsessed with Cat Nap, a band comprised of Fred Armisen, Carrie Brownstein and a kitty.

Wiig's obsession escalates quickly, from a big fan to a gun-toting, hostage taking maniac. Of course, Wiig plays it spectacularly. As she and Armisen are two breakout stars from "SNL," we're glad to finally get her on Lorne Michaels' other comedy show.

Fun fact: Wiig's Oscar nomination, for co-writing the screenplay of "Bridesmaids," earns her the distinction of being the first "Saturday Night Live" cast member to earn a nomination while serving as a cast member. (Of course, Bill Murray, Eddie Murphy and a few others were nominated well after their "SNL" stints.)

"Portlandia" airs on IFC on Fridays at 10 p.m. EST (9 p.m. central).
