Claytons is the brand name of a non-alcoholic, non-carbonated beverage coloured and packaged to resemble bottled whisky.
The product, bottled by Beecham, was taken off the market in New Zealand but continued to be distributed in Australia through Orlando Wines and later Cadbury-Schweppes.
Though the product is largely forgotten, the phrase "Claytons" has entered the Australian and New Zealand vernacular with two different, but related, meanings: The term is primarily used by people old enough to remember the original advertising campaign, but it is still widely used throughout both countries, especially in political debate.
Before turning to camera at the start of the ad, our Claytons-drinking hero (played by Jack Thompson) tells the punch-line of a joke to the barman: "... And then this guy says 'Now we can all get some sleep!'"
After completing a particularly irksome task – perhaps changing a tyre in the rain, or dropping 12 children off to their respective houses after a noisy birthday party – one can say "Now we can all get some sleep" to put a humorous full stop on the event.
