Epigram

Short poem with a clever twist at the end. Or, as [Samuel Coleridge]? said,

What is an Epigram? A dwarfish whole;
Its body brevity, and wit its soul.

Epigrams are among the best examples of the power of poetry to compress insight and wit:

Little strokes
Fell great oaks.
::::Benjamin Franklin

Here lies my wife: her let her lie!
Now she's at rest-and so am I.
::::[John Dryden]?
