They're in the serious business of news but the One News team showed they can still have a laugh, treating viewers to a surprise job swap on Friday night.
Mike Hosking took over Simon Dallow's role as newsreader, next to Wendy Petrie, leaving Dallow to introduce Seven Sharp for the night.
As he finished reading the sports news, Dallow turned to find the Seven Sharp co-host sitting in his chair.
"Hosking, get out of my seat!" he said in mock anger.
