Bill Maher and William Shatner talk about deep fundamental things while also being silly

 

This clip is two years old. I believe that Maher was 66 at the time and Shatner was 90. Here's the description that came with the clip: "Bill and William Shatner comically riff on the last acceptable prejudice, the spectrum of human sexuality, bad crowds in comedy, the making of Religious, and the origin of the universe." What kind of conversation is this? It seems to me that it's both real and an act. These guys are performers and they're certainly performing here, but I don't think they've got a script. They're just making it up as they go along. 

At the time I'm posting this, almost 800,000 people have watched this clip. What's is say or imply about the world that 800,000 people have found this entertaining?
