Can you put a price on the perfect athlete? In baseball you can, and that’s a $700 million dollar contract. Shoehi Ohtani took to the field in Seoul for the LA Dodgers to prove that the big cheque was worth it.

It has Marnie asking – can you predict if one of your kids will become the G.O.A.T – the Greatest of All Time in any sport? She’ll also be investigating the other kind of goat – I'd say ordinary, but these ones are fighting wildfires.

We bring you the curious tale of a never-before-seen beach pebble washing up on the shores of a remote island. What are they? And get the lowdown on the most unpleasant sounding ultramarathons after a 40-year-old Scottish woman completes a race SO hard that only 20 people have finished .

Plus, gravitational waves, home-grown antivenom, and listening on double speed. Can your brain take it?

Presented by Marnie Chesterton, Phillys Mwatee and Camilla Mota.

Produced by Harrison Lewis with Tom Bonnett, Jack Lee and Cath Mcghee.
