"If I was doing the sequel to Frozen, I would be a hero," Affleck joked. Affleck's two and a half year-old son specifically loves the song "Let It Go" and wants his dad to sing it for him any chance he gets.

Being a good dad, Affleck says he tries to sing the song, but he's not very good at it. His son even tells him that he's not as good as Fallon, who did a kiddie version of the song with Idina Menzel a few months back. "Do it like the man," his son tells him. "The man" being Fallon.
