What better way to end than with a poem...
So choose your axioms wisely my friend, examine them often for leaks.
Bail them out like a foundering float, burn the boat if it creaks.
Challenge the cherished old words, my friend, challenge the new ones too.
Avoid all beliefs that lead you to grief, and keep all the best ones for you.
OK, that was doggerel at best, so I take that back.
The best way to end is with the banana.
