Two police officers respond to a crime scene behind a grocery store. The homicide detective is already there. “What happened?” asks the first officer.

“Male, about twenty-five, covered in Raisin Bran and dead as a doornail.”

“Good grief,” says the second officer. “Didn't we have one covered in Frosted Flakes yesterday? And Captain Crunch last week?”

“You're right” said the detective, “I'm afraid this is the work of cereal killer.”
