"There are many words to learn and be amused. The first word is "abecedarian." The last word is "zzxjoanw." He recomends this word for Scrabble." (from an amazon review) [should you get this combination of letters (with a blank), a one in a googol chance, it could be successfully challenged anywhere in Known Space.]

the author, Peter Bowler, should have known better, as he is evidently an aussie.

this is still the best, last word on zzxjoanw:
