Two relatively intelligent and occasionally amusing guys talking about everything, anything and frequently nothing… What they lack in Talent they more than make up for with lack of preparedness. 
Remember the movie 
“my dinner with Andre“ of course not because you’re not 100 years old, but it’s sort of like that… Without all that wisdom and insight garbage. 
If you enjoy listening to them as much as they enjoy making it, then you’ll enjoy it twice as much as someone who hasn’t listened to it. That’s just simple math.
