OK, this is a short skit. Basically, the camera shows the first person perspective of someone walking through a small crowd of people outside a church (say, having just attended a wedding). You can hear the guy’s thoughts.
Guy (thinking): We all live in the real world.
Another guy: The real world? I don’t know anything about it!
Woman (in dull voice): Kant Just clapped.
Guy (thinking): German Idealism’s got it all upside-down.
Priest: Faggot!
