Actually, DJ used to refer to it as "Polish reversed lists", but 
whatever. ;-)

Man, if it weren't for that guy, *I* wouldn't understand this joke either...

It is not very common

I've always heard it as reverse polish LISP...

Who's DJ?  Also, I think reverse polish notation is the correct name for 
the postfix method of operator placement, and reverse polish LISP is 
rather the name for the programming language on HP calculators which 
used this notation (the calculators are stack-based).

David Jones. (Yes, that was his name.) Today we'd probably all call him 
Davy Jones. Which would probably puzzle the hell out of him.

He was one of the lecturers at college. If you want to know about the 
binomial theorum, or Dikjstra's shunting algorithm, or DeMorgan's 
theorum, or the vector cross product, this guy can tell you everything 
it is humanly possible to know, and how to apply it to any imaginable 
mathematical problem. Try to explain to him that you're taking down the 
B/W posters to replace them with colour versions of the same posters, 
and he looks at you like "wait... what?" Very strange.

Possibly not. Unless - like me - you build expression parsers just for 
giggles...

Or Bowie. I once met someone who knew him as Davie Jones.

Huh? No... but somehow I have the feeling that something's going over my 
head here.

Wait - is that "David Jones" as in "David E.H. Jones", aka "Daedalus"?

When I was a kid, there was a kind of scientific quiz show on German TV 
where a school class would compete with their (non-natural-science) 
teachers to explain entertaining physical (or sometimes chemical) 
experiments. That David Jones guy was a regular guest "experimentor" on 
the show (spoke quite a good German, except for his notoriously hoarse 
voice).

As "Daedalus", he also wrote about some "crazy" ideas that stuck in my 
mind, such as the "anti-greenhouse".

Could be that guy... an amazing "practical genius" if I'm asked.
