"whale" = something improbable; cock-and-bull story; falsehood, circa 1700?

[Joel S. Berson]

Does anyone have evidence of the use of "whale" to mean something 
improbable; cock-and-bull story; falsehood, in the period between 
c1600 and 1859, particularly around 1700?

c1600 -- A colleague provides the following for "Hamlet":

"Very like a whale.  Very much like a cock-and-bull story; a fudge. 
Hamlet chaffs Polonius by comparing a cloud to a camel, and then to a 
weasel, and when the courtier assents Hamlet adds, "or like a whale"; 
to which Polonius answers, "Very like a whale." (Act iii. 2.)"

[The next line is "Hamlet:  Then I will come to my mother by and 
by.  [Aside] They fool me to the top of my bent. I will come by and 
by."  That is, Hamlet sees the cloud/camel/weasel/whale as an attempt 
at deception.  The OED accepts this interpretation of "very like a 
whale"; see sense 5.a.]
