"The tables have Turn-bulled, now it's Shorten's house".

So rapped Labor leader Bill Shorten on Friday morning, the culmination of an out-dagging competition taking place between the Opposition Leader and Prime Minister over the past week, as they traded policy for rhyme in the race to win Australia's popular FM radio and commercial television markets.

US rapper Macklemore's performance at the NRL grand final on Saturday has triggered more than just a national debate over freedom of speech and same-sex marriage.

It's pushed Mr Turnbull to suddenly "grieve for Tupac," and Mr Shorten to claim: "he's the cat, you're the mouse".
