Writing Stragegies: What is a Clerihew?

My own clerihew:

Economist Adam Smith
Taught facts not myth
To be rich here and in hell
Your skills or products sell

In the book A Jacques Barzun Reader I found
the following definition of a clerihew:

Which is of all the kinds of verse
The most informative and terse:
One line invokes a well-known named,
Three more disclose, for praise or blame,
In words that make one want to quote,
A single vivid anecdote.

Post your clerihew here--they are more fun
than Haikus.
