Of course, the pandemic and subsequent lockdowns made a feature. And the rap featured references to some notable political moments of the year, like when Judith Collins was rolled as the National Party leader and Chris Hipkins' "spread your legs" blunder.
And Jono and Ben reminded listeners of major world events too, like the ship that was stuck in the Suez canal, and President Joe Biden's accidental snub of Aussie Prime Minister Scott Morrison.
Who could forget the biggest entertainment moments too? From the Friends reunion, to Kim and Kanye calling it quits, to Adele returning with her first album in six years, the rap has it all. Of course, Oprah's interview with Prince Harry and Meghan Markle makes an appearance too.
For keen New Years' festival fans, the reminder about Rhythm and Vines being canned might be too close to home.
Jono and Ben ended the 2021 wrap-up with a plea for the Omicron variant of Covid-19 to keep away.
