Ancient Lisp history on TV

From some comp.lang.lisp spelunking, a particular author stood out a bit:

I happened to have taped this episode for later viewing, so I paid close
attention to the Lisp stuff.  Here's what I was able to get.

        [... top of screen ...]
           (APPEND ! (REVERSE !) !))
        (DEFUN FAIL/ROME (!)                    ; this line is unclear
          (REVERSE ! (REVERSE 2) 2))            ; this line is unclear
        (DEFUN F-TO-C (F)
          (- (/ (* (- F 40) 5) 9) 40))          ; sic!
        (DEFUN C-TO-F (C)
          (- (/ (* (+ C 40) 5) 9) 40))          ; sic!
        [...end of screen...]

Now, I'm willing to give whoever did these screens the benefit of the
doubt and assume that the errors in F-TO-C and C-TO-F are the result of
my VCR rather than actual errors in the function.  (Though I feel quite
confident that the "5" and"9" are definitely backwards in C-TO-F.)

I'm pretty sure that FAIL/ROME is wrongly transcribed, but it's the
best I can make out on my VCR.  (Hey, I recorded it at low speed, okay?
I didn't expect there to be HIDDEN MESSAGES or anything.)

Later, as Lucas tries to sanitize the Brazilian elections, the info box
next to map of Brazil fills up with

        (MAKE-INSTANCE 'ACCESS-LINE

the remainder of the line is cut off by the edge of the screen.

I find it an interesting stylistic point that ! is used as a variable name.
Is this common?
