Summary The night after a pretty terrible experiment -- the YouTube Special -- host Nick Cannon did everything he could to entice viewers to stay tuned, including teasing us about another twist that would be announced later in the show.

Sharon Osbourne said the show took a risk, stopping short of calling it a failure. She instead chose to focus on some of the magical moments she said happened.

To the results: Nick called for the first handful of acts to come to the stage: Accordion playing dog Pup, pizza dough juggler Pizza Patt, pianist Maestro Alexander Bui and comedian Austin Anderson. Sharon said she couldnt decide who America had chosen. After the seemingly obvious choice (from that bunch, anyway) of Maestro Alexander Bui was announced, Piers said he was baffled by Sharons hesitation. He said Alexander was the only true talent on the stage, standing among a guy whos not funny, a dog that didnt play the accordion, and a bloke who chucks pizzas in the air. He then encouraged Alexander to play a more recognizable classical piece next week.

Be our guest: In continuing the YouTube theme of the week, the AGT stage welcomed back Quick Change, the wardrobe changing wonders who burned up the viral video site with more than 21 million views of their original Talent performance. Next, motivational-speaker-turned-YouTube sensation Judson Laipply brought his Evolution of Dance to the stage.

Later, Taiwanese TV singing contestant Lin Yu Chun paid a visit to perform his rendition of Whitney Houstons I Will Always Love You, which has topped 10 million views on YouTube.

Back to the results: Nick called the next group of acts -- kid dancer Dylan Plummer, dark illusionist Dan Sperry and dancer Booker Forte -- to the stage. The act that moved on was Dan Sperry, and the announcement sent Howie back into the rafters. Dan thanked America for responding in such a positive way to his act that he acknowledges is dark and can put off a lot of people.

Later, Nick called dancer/mover Ryan Rodriguez and 10-year-old operatic singer Jackie Evancho to the stage with one spot in the semifinals on the line. Jackie moved on, sending Ryan home. Howie said he was delighted, but that people have asked him since Tuesday night whether Jackies voice was real. To prove it, he asked her to sing an impromptu note, which she did.

Finally, Nick called for PLUtonic, Cam Hodges and Kristina Young. The first act leaving the competition was PLUtonic.

That meant the decision over who stays between Cam and Kristina was left to the judges. Howie said he liked them both, but had to go with his gut and his gut said Cam was he bigger star with the most potential. Sharon said Kristina was very viable as an artist, so she picked Kristina.

Piers had the tiebreaking vote and said he had to take a bet on one of the singers in guessing which of them could go the furthest. He said the act he suspected could deliver better than last night was Kristina, so he picked her.

Nick finally announced the twist, which is that next weeks episode is a wild card show in which some of the judges and Americas favorites will return for another shot at the semifinals.
