Crocodile tears (or superficial sympathy) are a false or insincere display of emotion such as a hypocrite crying fake tears of grief. The phrase gives its name to Bogorad's syndrome, colloquially "crocodile tears syndrome", an uncommon consequence of recovery from Bell's palsy where faulty regeneration of the facial nerve causes sufferers to shed tears while eating.
History and usage 
The expression comes from an ancient anecdote that crocodiles weep in order to lure their prey, or that they cry for the victims they are eating. The earliest known version of the anecdote is found in Bibliotheca by Photios, then in a number of bestiaries such as De bestiis et aliis rebus. This tale was first spread widely in English in the stories of the travels of Sir John Mandeville in the 14th century.
|“||In that country and by all Inde be great plenty of cockodrills, that is a manner of a long serpent, as I have said before. And in the night they dwell in the water, and on the day upon the land, in rocks and in caves. And they eat no meat in all the winter, but they lie as in a dream, as do the serpents. These serpents slay men, and they eat them weeping; and when they eat they move the over jaw, and not the nether jaw, and they have no tongue.||”|
An alternate explanation for the expression's origin is that crocodile tears cannot be authentic because crocodiles cannot cry; they lack tear ducts. Yet this is a myth: Crocodiles possess lacrimal glands which secrete a proteinaceous fluid, just like in humans, though tears will only be visible after a crocodile is out of the water for a prolonged period of time, and the eyes begin to dry out. However, while crocodiles can and do generate tears, they do not actually cry.
|“||O devil, devil!
If that the earth could teem with woman's tears,
Each drop she falls would prove a crocodile.
Out of my sight!
Again, Shakespeare, in an earlier play, Henry VI, part 2, Act III, Scene i
|“||...and Gloucester's show
Beguiles him as the mournful crocodile
With sorrow, snares relenting passengers;
And in Shakespeare's Antony and Cleopatra, Act II, Scene vii
|“||LEPIDUS: What manner o' thing is your crocodile?
ANTONY: It is shaped, sir, like itself; and it is as broad as it hath breadth: it is just so high as it is, and moves with its own organs: it lives by that which nourisheth it; and the elements once out of it, it transmigrates.
LEPIDUS: What colour is it of?
ANTONY: Of it own colour too.
LEPIDUS: 'Tis a strange serpent.
ANTONY: 'Tis so. And the tears of it are wet.
