Shorten was touring a school in Queanbeyan on Wednesday morning when he asked a little girl named Angelina what she had been given for Christmas.
Angelina said she was given a karaoke machine and her favourite song to sing was 'Let It Go'.
Sensing an opening the opposition leader dropped some 'Frozen' knowledge that Angelina didn't even know about.
Here's the transcript:
Bill: Do you like doing karaoke?
Agelina: Yep
Bill: Are you going to see the next 'Frozen' film when it comes out?
Angelina: Yep
Bill: Have you seen that little short film 'Frozen Fever' yet?
Angelina: Nope
Bill: They made a little, like short sort of film. But 'Frozen' (2) comes out in the middle of this year.
