Proof from America's Test Kitchen is a new-ish show trying to solve some food mysteries. Like should you put ketchup on burgers, and how do odd jellybean flavours get designed?! Writer and producer Maya Kroth shares her love of celery with Proof's host Bridget Lancaster, including stories from celery's golden age in Victorian times when it was a status symbol costing more than caviar! And in 'Beanboozeld, Part 2', Sara Joyner investigates how people design weird jelly bean flavours, with her...

For a few years back in the 1980s and 90s, McDonald's sold pizza at some of its restaurants. Then it stopped doing so. These simple facts have propelled Brian Thompson into an investigation spanning years and 105 podcast episodes as he tries to answer the question- 'Whatever Happened to Pizza at McDonald's?'

Auckland's Fringe Festival gets started next week and one of the many weird wacky shows on display is Amy Mansfield's I Didn't Invite You Here to Lecture Me.

She joins us to talk about the show, what people can expect, and why hoarding is SOMETIMES a good idea...
