I am fond of clerihews, which involve famous people in the first line, and then a rhyme, and then two clincher lines that define or describe the person comically.
For instance:
John Milton
Never stayed at a Hilton
Hotel
Which is just as well.

or:
John Stuart Mill
by an effort of will,
gave up his natural bonhomie,
and wrote Principles of Political Economy.

Mudcat clerihews:

Joe Offer
Always seems to proffer
Good sense,
Over the Mudcat fence.

Catspaw,
Has only one flaw
It involves doing things heinous
With a possum's anus.

and so on. Yours, Peter T.
