Euuh ... this 'charming' gentlemen seems to have gained quite a bit of popularity. When I was young, we used to make jokes about the elderly talking about the war or any other story from the old days. Two learnings:
1. It's more important for entertainment to be genuine then for it to be professional.
2. I guess this is another example of "The Long Tail". In my opinion this is damn boring stuff, but in the long tail of YouTubers, there is a considerable number who actually enjoy this. Great for them, let them have fun!
