I always seem to get a fair chuckle from the political satire placed into cleverly thought out arrangements of animals. Dr. Orwell seemed to have his cards on the table, I'll tell you that. And if that should fail, there is always the good natured platypus; the preposterous undersea mammal who continues to fascinate and defy the regulations of its kingdom.
I recently read one about Facebook and Twitter. It was hilarious. It would be an easy topic to write a funny monologue about. : )
