During Queens of the Stone Age's headline set at Splendour in the Grass on Saturday one fan got on the shoulders of a friend and flipped off frontman Josh Homme.
But Homme was having none of it. "It's past your fucking bed time son," said Homme as he dressed down the bird flipper in front of a crowd of 27 000, that included members of the xx, Royal Blood and King Gizzard and the Lizard Wizard.
The lesson learned here is to not to mess with the large red-haired rocker when he's at work.
