sardonic:From the Online Etymology Dictionary.
1638, from Fr. sardonique (16c.), from L. sardonius (but as if from L. *sardonicus) in Sardonius risus, loan-translation of Gk. sardonios (gelos) "of bitter or scornful (laughter)," altered from Homeric sardanios (of uncertain origin) by influence of Sardonios "Sardinian," because the Greeks believed that eating a certain plant they called sardonion (lit. "plant from Sardinia,") caused facial convulsions resembling those of sardonic laughter, usually followed by death.
This is "The laughter". An ironic view of it; I don't like that perspective either. I was about to use a quote from The Praise of Folly by Desiderius Erasmus, but would be too much.
