Khloe's still backstage, where I'm starting to think she should spend a lot more time, and the cameras should spend a lot less. Simon gets the floor and announces, "The movie is Mary Poppins; the group are Lyric 145." Can't wait to hear their hip-hop version of "Chim Chim Cheree" or "Supercalifragilisticexpialidocious." Wait, what, they're actually doing that second one? Simon appears to have his Disney movies mixed up, starting them off dressed for Alice's mad tea party behind a table that turns out to be packed with dancers. And of course he also has them dressed like demented clowns again, with a stage and lighting design that expresses every last erg of Simon's pent-up rage at the world's epileptics. At one point, Lyric Da Queen leans over on the judges' table and teases L.A. about how she can even say "Supercalifragilisticexpialidocious" backwards, but that would be going a little too far. And one of the guys says, "One night I said it to Britney and now she's my wife." Clearly Simon's goal with this group is to invent a weapon of mass headache-inducement. When the torture finally ends, L.A. goes first, telling the table-mic that Lyric broke for him that he hated it, but it was perfect. Britney liked the theatrics (which, agreed, were amped up enough to penetrate even the thickest Thorazine haze), and Demi says to Simon, "Who knew that in that rusty old brain there were some fresh, cool, hip thoughts?" Is that what we've just learned? Simon reveals that Lyric picked the song, and it was "bloody fantastic." I think I may be losing my mind here.

Britney gets to introduce her mistake from last week that was so egregious she earned an automatic do-over, Diamond White. In her intro reel, Diamond says her elimination was the worst day of her life. She cried through what she thought was her last interview, and then got the call from Britney -- on camera -- telling her she was the one who was too good to let go. So now she's back, singing "I Have Nothing" by Whitney Houston. She must have been brought back in just the last couple of days, because the production is pretty much limited to a light show and the white suit that's wearing her. As for her singing, she's clearly got something to prove, and I'd say she proved it. L.A. says it was an ambitious song choice, but she "brought it home." Demi confesses to being near tears and doesn't have much else to add, and Simon says he's so happy she's back. Britney tells her that Whitney would be very proud. Hard to say how long it will be until Britney gets to ask Whitney herself.
