"So John, in your tenancy as Prime Minister there were ups and there were downs," begins Key.
"We're talking when you said "trotey" in front of the entire world - not your finest moment - there was the three-man handshake, there was the infamous hot dog we all know about."
Sir John grimaces as he is reminded about moments he would perhaps prefer were forgotten. They include creating the new word "trotey" during the opening ceremony of the 2011 Rugby World Cup and the awkward three-way handshake with Richie McCaw and International Rugby Board chairman Bernard Lapasset during the final Cup presentation.
"So why we are here today is we want to know with the 2017 election coming up, we're talking National, we're talking Labour, we want to know as former prime minister who you think is going to win the 2017 election," finished Max.
As Sir John launches into the answer he is cut short after two words as the stop clock winds down.
It's not the first time Sir John has featured on social media with his son. In 2011 Max Key posted a Facebook photo of himself planking in the family lounge with his father in the background.
