Not to take away from the side splitting hilariousness of this novel meme, but I just noticed Lisp is actually one of the few languages where you can't add spurious parentheses. If you find that a, (a), ((a)), etc are equivalent, it's probably not Lisp you're looking at.

Unless a is a function that returns itself

In Scheme or Clojure, but not in Common Lisp. Now, should we adopt this parentheses-exacticity as part of the definition what is a real Lisp?

P.S. Of course, a Lisp-2 saves us only from an unlimited proliferation of parentheses, but a simple (defmacro foo () 'foo) will allow you to get a couple whenever really needed.
