Last night, former cast member Dana Carvey (inexplicably) came back to host Saturday Night Live. It was a nostalgia-tinged evening, opening with the semi-triumphant return of Wayne's World; while Carvey slipped right back into his old shoes, Mike Myers seemed a bit off-key, as Garth and Wayne chatted about the Oscars and riffed on "Winter's Bone." Later, Carvey also reprised his beloved Church Lady, which was more successfully executed, and included an appearance by living moppet Justin Bieber, with angel halo glow to boot. The monologue was surprisingly painful however, only briefly rescued by an excellent Jon Lovitz cameo. Click through for Wayne's World, Church Lady, a parody of The Roommate featuring Bieber, a "Bad News" commercial, and James Franco on Weekend Update.
