On June 19, 2007, Fator made his first national appearance on America's Got Talent. Speaking on the experience, he said, "Not in my wildest dreams did I imagine I would win that show ... Essentially I auditioned because the guy that was the ventriloquist the first season got on Late Show with David Letterman... So I figured I'd do three episodes like he did and end up on 'David Letterman'." After winning the show, Fator actually had to turn the Letterman gig down fourteen times before his schedule was clear so he could appear. "My schedule got so packed, and it broke my heart every time I had to turn him down," Fator says.
It was announced on the show that in conjunction with winning, he was to appear at the Jubilee Theatre at Bally's Las Vegas. However, the spots were only going to be 15 minutes long, and in complete mutual cooperation with his management team and Bally's, the plan was dropped. Fator performed at Christian rock legend Larry Norman's 60th birthday party in April 2007. Later Fator flew Larry to tapings of America's Got Talent and also to his debut show at the Las Vegas Hilton as an honored guest. Norman told friends shortly before his death that it was one of the most fun years of his life.
In early December 2007, Fator signed a contract for $1.5 million with the Las Vegas Hilton to do three shows a month from January 2008 to May 2008. Fator also performed a 6 p.m. early family New Year's Eve show on December 31, 2007.
In 2007, Fator became an official supporter of Ronald McDonald House Charities and is a member of their celebrity board, called the Friends of RMHC.
In July 2007 Fator appeared in Montana to raise funds for the Kidsports Sports Complex in Kalispell and said he wanted to come back in 2008 to do another show. “We thought, we bet he wants to, but we bet he won’t have time,” said Nancy Manning of Rotary Club of Kalispell. “He made time because it’s so important to him.” All proceeds from Fator’s show went towards the field.
In 2007 Fator performed a benefit for families of miners in Huntington, Utah.
On September 3, 2007, Fator made a special appearance in the Jerry Lewis MDA Telethon at the South Point Hotel and Casino in Las Vegas, thanking the crowd for the support. He brought back Emma Taylor to sing "At Last" and Winston the Turtle to sing "What a Wonderful World". He returned to the Telethon on September 1, 2008 and brought Julius to sing "Only You" from The Platters, Marvin Gaye's song, "Let's Get It On," and "Crazy" by Gnarls Barkley. Maynard Thomkins was also brought on to sing "Viva Las Vegas" to finish the show. Fator made his 3rd consecutive telethon appearance (this time via satellite from his showroom during a performance of his show) on September 6, 2009 with puppets The Fifth Beatle and Vikki The Cougar with special guests The Commodores, who joined Fator performing "Brick House".
