They have a radio series called A History of the World in 100 Objects. Throughout the museum, they have the 100 objects and a brief reason why it's included. I didn't see them all, only a few. That Easter Island statue is one of them.
Not on a Disney Channel show, but you definately could on a Nickelodeon show.
There's a few episodes of Lizzie McGuire where they say "oh my God". One I remember is the one where the gang go to watch a pre-school show that's on tour, Lizzie wins the gift basket and finds Claire there with her sister, and then spreads the news around that they saw it.
