What are 3 puns in Great Expectations?I have been asked to find 3 puns in Great Expectations. I found one about the tickler (the whip), and 1 about...

A pun is usually the humorous use of a word to suggest two
or more meanings at the same time. 

• Known for
  his disdain of what he considered a frivolous aristocracy in England, Charles Dickens
  often satirizes those who admire and imitate this upper class.  For instance,
  when Herbert Pocket introduces Pip to Sarah Pocket, the wife of the unprepossing Matthew
  Pocket, she In Chapter 25aspires to this class and does little but read from a book of
  titles while her children tumble all over her. Pip watches the children tumble and be
  kicked around; then, he remarks that they appear to be "tumbling up."  The play upon
  tumble is that Mrs. Pocket does not work for her position; she
  "tumbles" into it.  She also fumbles at raising children; instead they are raised by
  nannies, who are superior in training their own children rather than their
  own.


• In Chapter 25, Wemmick, the secretary to Mr.
  Jaggers, takes Pip home with him.  There, Pip observes how Wemmick cares for his
  father.  He even has a cannon to go off every
  night.

At last, when we got to his place of business
and he pulled out his key from his coat-collar, he looked as unconscious of his Walworth
property as if the Castle and the drawbridge and the arbour and the lake and the
fountain and the Aged, had all been blown into space together by the last discharge of
the Stinger.  [the cord of the cannon is what the Stinger
is termed.  Also, a stinger is the end of the bumble
bee]

  table,

There were three ladies in the room and one
gentleman. Before I had been standing at the window five minutes, they somehow conveyed
to me that they were all toadies and humbugs, but that each
of them pretended not to know that the others were toadies and humbugs: because the
admission that he or she did know it, would have made him or her out to be a toady and
humbug.

A toady is both a
flatterer and a creature who sits and waits until something lands or dies near him;
then, he swallows  it. The pun upon the word toady is that Camilla
and Sarah Pocket are flatterers of Miss Havisham while at the same time they sit and
wait for her to die.

In addition to these, there
are several other puns in Great Expectations.  Like many Britishers, Dickens enjoyed
satire and pun, "the lowest form of wit" said Shakespeare who entertained his
groundlings with them.
