The RE Teacher calls in Johnny's mother to complain about his behaviour in class.
"When I asked him who knocked down the Wall of Jericho he said, "Please Sir, It Wasn't me." "
"Listen," says Johnny's mother. "If my boy says he didn't do, it then he didn't do it! OK?"
teacher then complains to the headmaster who says 'well what's this wall going to cost to repair anyway"
A longer and funnier version ('cos it involves more characters) can be found on Mike Harding's
"A Lancashire Lad" LP from 1972 - couldn't find this particular track from a brief look on YouTube, but it's probably there somewhere in the middle of a long set. Gist is that MH is teaching in St Emmanuel Cohen's on Cheetham Hill when the schools inspector turns up and wants to ask his brightest pupil a question. Here's a much abbreviated rough transcript.
"There's no brightest here, it's class 14Z - ask him over there, then you won't wake the others up".
"Who knocked down the walls of Jericho?"
"Not me sir, I was in our house watching Banana Splits."
"Teacher, what do you have to say about that?"
"Well, he's a good lad, that one. If he says it wasn't him it must have been someone else."
Inspector goes to see headmaster:
"Mr Harding's a good judge of character. If he says t'lad didn't do it, he's probably right."
By now furious, inspector hops on his penny farthing and rides into town to complain to his boss, Miss Pringle, who confirms that she has no problem with the headmaster and his staff and adds:
"Don't release this to the press, we'll get a couple of brickies round in the morning and have it back up again in no time."
