The group in the movie originally called themselves the 1-ders, or the One-ders. In the movie, Hanks was the manager that handled the group, and he made them change their name to Wonders. No idea what he’s referencing.
Maybe insinuating DJT will be a "one-term" president? Or referencing "The One" (Obama)?
FWIW, he and Rita must've gotten the really good stuff down under to bounce back like that. Connections have their privileges.
K, thanks.
Many such references are lost on me.
