Even though Jon Hamm was in the audience as a back-up host should last night's SNL have gone off the rails, not even the cameo-happy actor's lover's quarrel with a Bobby Moynihan Snooki or Bill Hader's Norman Bates-inspired impression of Shephard Smith could salvage Lindsay Lohan's mostly unfunny return to the show. One exception, of course, was the Real Housewives of Disney sketch, in which Lohan plays a weave-wearing Rapunzel, which might not be too terrible a concept for a Lohan-starring vehicle that will help launch her straight-to-DVD career renaissance.
