He was known for his immaculate comic timing as a television presenter.
And following his death this week at age 87, archive footage has resurfaced of John Hamblin's loosest moments from his time as a host of ABC's Play School.
The hilarious outtakes, which never made it to air for obvious reasons, were released for the show's 50th anniversary in 2016.
'Mistakes were part of the magic formula, but there were some bloopers that had to be edited out,' a narrator said when the clips were first aired six years ago.
Hamblin wasn't shy with innuendos, and in one outtake was shown lying on the floor while a producer interrupted the scene to give him a pillow.
The producer said, 'We'll get you a cushion on the floor,' to which Hamblin replied with a cheeky smile: 'Who wants to be first?'
Hamblin also once tested out a poorly constructed slide made out of cardboard and pipes. Despite his co-hosts urging him to stop, he dove onto it causing it to collapse.
Children's rhyming songs were another part of the show that resulted in some funny outtakes, with the tongue-twisters resulting in accidental expletives.
Hamblin died at the age of 87 on Wednesday.
The ABC paid tribute to his 'comedic timing and wit', saying he 'helped cement Play School as one of Australia's most cherished children's programs'.
Hamblin joined the iconic children's show in 1970s and soon became a fan favourite. He starred in more than 350 episodes of the program across a 30-year period.
He was known affectionately as 'Naughty John' during his run for his cheeky sense of humour and irreverent nature.
After his retirement in 1999, Hamblin returned as a special guest for Play School's 50th anniversary special in 2016.
Jennifer Collins, ABC Director Entertainment & Specialist, said in a statement: 'John was an unforgettable presenter whose comedic timing and wit helped cement Play School as one of Australia's most cherished children's programs.
'John had a wicked sense of humour and was not afraid of a double-entendre. His presence always managed to keep both our toddler target audience and their parents equally engaged with the show.
'I would like to extend my condolences to John's family at this sad time.'
Aside from his role in Play School, Hamblin was also an accomplished actor.
He had roles on Number 96, Class of '74, The Young Doctors and Case for the Defence in the 1970s, and in his later career starred in Sons and Daughters, All Saints and Love My Way.
He memorably played Michael Chamberlain in the 1984 television movie The Disappearance of Azaria Chamberlain.
News of Hamblin's death led to a flood of tributes on social media.
'One of the best Play School presenters,' one fan wrote on Facebook.
'Vale John Hamblin. We loved you, over multiple generations, in our family. Thanks for all your playful good humour,' another posted to Twitter.
'An iconic part of my childhood and many others'. Thank you, John Hamblin. Go well,' added a third.
'Thank you John Hamblin for your wonderful wit, love and joy in teaching young children, and for all the double entendres keeping the adults entertained at the same time,' one viewer commented.
'This is breaking my heart a little bit. John Hamblin loomed large in my childhood,' said another.
John is survived by his children Emma and Myles.
