The pair spent the entire episode relentlessly mocking one another, but it all came to a head when Adams suggested they name a portaloo after Moa with the tagline, "Come and give me some Moa poo".
They exchanged jabs - including a sassy "Don't hate me 'cause you ain't me, honey" from Adams - until Moa had to admit Adams was on fire.
"You're the most entertaining guest we've had...You know what? You could actually do this for a living, you could be me."
Adams simply responded: "I'd be a lot more gorgeous than you".
There were height jokes, shotput lessons and a even a group singalong but most interestingly, Moa used her psychic powers to predict the sex of Adams' baby.
