Who originally said this?
"Of all the words of mice and men, the saddest are 'what might have been".

Best Answer: The "mice and men" version does appear in Vonnegut's novel "Cat's Cradle", but Vonnegut is paraphrasing this ...
For of all sad words of tongue or pen
The saddest are these: "It might have been!"
... from an 1856 poem, "Maud Muller" by John Greenleaf Whittier.

Vonnegut was probably conflating the Maud Muller lines with Robert Burns' "The best laid schemes o' mice an' men / Gang aft agley".
