Going to a cannabis factory with your mum doesn’t sound like a fun day out. But it’s the sort of mischief Russell and Ninette Howard get up to as they return to the States for another run of their US road trip. The first port of call is Portland, Oregon, where recreational use of cannabis has recently been made legal. The duo embark on buying it, smoking it and even eating it - with mildly amusing consequences. Russell seems eternally perplexed by and slightly exasperated with his dear mum, who frequently upstages her son with scene-stealing one-liners. When it comes to trying the drug, for example, she has one key question: “Will it make my bunions stop hurting?”

The comedian and his mother head to Las Vegas to help judge the Mrs Globe Beauty Pageant, but Russell must first understand what it takes to be a beauty queen.

Russell and his mum are enrolling in the Rock and Roll Fantasy Camp, where they have 48 hours to become full blown guitar heroes and perform their first ever gig in the heart of Hollywood.

The comedian and Ninette head to cowboy country, where they saddle up for a mission to become real life ranchers.

The comedian and Ninette head to Naples in Florida, to try to find out why its was voted the happiest city in America.

It's the 4th of July so Russell and his mum, Ninette, are visiting an All-American State Fair in Indiana to join in the celebrations. However their Independence Day is going to be anything but traditional as they have been invited to run away with the circus for the weekend and join an old fashioned American Side Show.
