"Glee was good," Fatone, 33, Tweeted after last week's show, "but I think my a-- needs to get on that show a be a teacher."
He's also convinced the band's music would be a perfect fit for the FOX show. "I saw the Britney Spears one and I thought it was kind of cool," he told PEOPLE at Orlando's World Smile Day festivities, benefitting the Smile Train organization. "I said, 'You know what? They should do an 'NSYNC one.' So I mentioned it on Twitter, and everyone is retweeting it and saying, 'That would be great!'"
He adds: "I love acting and I like to sing. It'd be perfect! Seriously, it's a great show. I'm a fan."
Although the birth of his second daughter, Kloey, has kept him busy this year, Fatone wants to explore some new opportunities. "Everybody's healthy," he said. "So now it's time to get back to work."
If he doe get 'NSYNC on the show, what would be the big number? "Wow, I don't know," he says. "Probably 'Bye Bye Bye.' Or maybe even 'It's Gonna Be Me.' You never know with Glee. They can go so many ways to tell their stories with our songs."
