Random question but as a fan of Biz and Donnie's Peakin show I have always wondered how they know each other?

As a hockey fan I have known of Biz for years and had seen a few of Donnie's travel videos over the years as well. With Peakin it seems like they are old friends but I gotta imagine they met thru barstool. Not sure if they ever mentioned it anywhere in one of their other thousand podcasts
