From the syndicated comic strip 9 Chickweed Lane by Brooke McEldowney, 2007-02-03 (one of a series of strips labelled "A Locutionary Field Guide to Earth (the hard little planet with the soft center)"):
Deceit, noun:
A dog rolls on the carcass of a dead possum in order to deceive other animals regarding his identity as a dog.
A man lolls in the scents of a church in order to deceive himself regarding his identity as a thief, an adulterer, and a liar.
The difference is that the dog does not first have to endure being bored by the possum.
