Ben Patterson writes in Leadership:

Sam Shoemaker told of a near-sighted professor who was an expert in entomology. His office walls were covered with pinned and framed insects. One day his students decided to play a practical joke. They took the body of one bug, the legs of another, and the head of yet another and glued them all together.

The specimen was brought to the professor for identification. "What kind of bug is this?" they asked.

The professor eyed the bug closely and finally replied, "Gentlemen, this is a humbug!"

Shoemaker drew the analogy to a person whose heart belongs to King Jesus, but whose head is run by the world and hands are run by the devil.

That, too, is not something God created. Anyone watching someone like that would have to say , "This is humbug!"
