Is it "hilarious"? Either "surreal" or "disorienting" would seem to be more likely reactions, but that's just me. Also, given that the Combat Zone was done by 1995 and, realistically, no one under 15 was there, you've inadvertently self-identified as being 40+. Which is fine, of course (I also find myself in that cohort).
But, it's worth remembering, for every single person under 40, the Combat Zone is merely relevant in terms of "oh, I think I saw a photo of it once on Dirty Old Boston's Instagram page?" If that. Look around those streets these days and speculate on how many of the pedestrians are under 40... I think it's a very sizable proportion, given the college campuses, etc.
All of which is to say: what IS probably hilarious is the disconnect between the amount of time Bostonians 40+ spend meditating and arguing about the meaning and legacy of the Combat Zone... and how Bostonians under 40 don't.
