Watch Kristen Wiig's "SNL" promo videos here Kristen Wiig is back hosting "Saturday Night Live" for the first time since she left the show in May 2012, and we couldn't be more excited about her return, as is Fred Armisen from what we can gather from the promo videos below. They're funny. Watch them. Trust us. Enough said. Tune in to NBC this Saturday at 11:30 p.m. ET to catch the "Bridesmaids" star's much-anticipated return to "SNL."
