The visiting Bible school supervisor asks little Johnny during Bible class, "Who broke down the walls of Jericho?"
Little Johnny replies, "I dunno, but it wasn't me!"
The supervisor, taken aback by Johnny's lack of basic Bible knowledge goes to the school principal and relates the whole incident.
The principal replies, "I know Little Johnny as well as his whole family very well and can vouch for them; if Little Johnny said that he did not do it, then I, as principal is satisfied that it is the truth."
Even more appalled, the inspector goes to the regional Head of Education and relates the whole story...
After listening he replies: "I can't see why you are making such a big issue out of this; just get three quotes and fix the wall!"
No Tail Light
"How long have you been driving without a tail light?" asked the policeman after pulling over a motorist.
The driver jumped out, ran to the rear of his car, and gave a long, painful groan.
He seemed so upset that the cop was moved to ease up on him a bit.
"Come on, now," he said, "you don't have to take it so hard. It isn't that serious."
"It isn't?" cried the motorist. "Then you know what happened to my boat and trailer?"
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. I'm afraid," said the detective as he took a drag from his cigar, "this is the work of a cereal killer."
