I read a page of some of the best & cleverest crytpic crossword clues and answers in a trivia book about 20 years ago. I wrote them down on the back of two scrap library catalogue cards and kept them, but could only ever find the answers and not the clues after that.

I remember a couple of them:

Clue 1:   Orphan has neither view

Clue 2: What the Greek tailor said

(and I just found a reply from the Greek customer)

Clue 3: She, too great for words, can never have children

There were more but I can't remember them at the moment.
