Comedian, author and lover of words Colm O'Regan joined Calvin as a stand in host this week. He shared his story of going from a human scarecrow to selling smut and everything in between. In Colm's latest book 'Gallivanting with Words' he traces the origin of words like 'shifting' and 'moth' and he explained why he loves slang so much and why he want's to find the first person to ever say 'Yup'.

Colm has his own podcast too A Few Scoops with another former guest of the podcast, Aoife Moore, which you can check out now.
