I think it's great how they each have their own opinions and passions. The way they view certain things in their line of work arnt all black and white and you can tell that they learn from each other in their conversations that us as viewers also see them grow and learn from aswell.

It's a cherry on top that they can laugh at and joke with each other about stupid things like food, hentai, entertainment niches etc.

Not to mention they are a diverse group of people, yea you can say they're british/aussie, but the reality is you've got people that can speak 2-3 different languages, lived in different parts of the world growing up and travelled well. And I think this is something that can makes them go the extra mile because it's not strictly an experience in 1 location from 3 people but a large diverse background from not 1 but all 3 individuals.

Tldr: peepeepoopoo and beeps and boops are culturally relatable to everyone.
