Australian fans of the American comedy show 2 Broke Girls responded in uproar over the racist joke about Indigenous Australians, which aired on Tuesday evening.

During the season four episode, titled And the Fun Factory, a male character is shown chatting up an Australian woman online before explaining, "She's part Aboriginal but has a great personality", to a friend.

Social media sites such as Facebook, Twitter and Reddit have been swamped with angry people, and those defending the racial slur joke.

"How dare you make such a racist disgusting joke about Aboriginals. If it had been said about an African American it would never have made it to screen. Not impressed!" wrote an Adelaide-based fan posted to the show's Facebook page.
