Other words rhyming with Pony, apart from "boney", are baloney, Police Academy's Mahoney, Island (Coney), most pastas, and homey. I just wrote this.
My little Pony,
Just like Mahoney,
She's got a homey,
Makes helicopter noises that are phony.
And that's the best My Little Pony rhyme ever. SUBJECT CLOSED.

With the kind of pretention born of being a selective school in the middle of a shithole, my school insisted that pupils write only using fountain pens. Our revenge for having to use these archaic devices was to flick wet ink trails up the back of Mr Worth's jacket when he bent down to help the kid in front. When the poor bastard switched from his blue-streaked grey jacket to a new navy blue one, we switched to black ink.

Another way of calling your friends gay. Originates from our headmaster - Mr Archer - who was apparently caught bumming off another man in some public toilets.

I did Cascaid - and take serious issue with the 'aid' part of the name. It told me to be a Pet Shop Owner. I am a magazine editor.

An instance of desk-writing, which evolved into a strange kind of soap-opera. One morning, we found written on one of our desks, "Yesterday my girlfriend sucked my cock" in big black letters with a ring round it. The next day, a smaller ring had attached itself to the first, containing the words, "Today I took her from behind." The next day: "I took her from the front." Each day new messages were added, until the entire desk was covered. Some gems I have remembered included, "I like shaved pussies," the contradictory "actually I like hairy pussies best," and the informative "There are several meanings for the word 'pussy.'"

Meadowbank station (in Sydney) used to change their signs on quite a regular basis. They seem to have given up these days.

"Please vacate this seat for elderly or disabled passengers" can also be made into "Please eat elderly or disabled passengers", with hilarious consequences.

Two teams, one playground/car park. One (unopened) can of coke. The can is thrown back and forth, and must keep moving until it's empty. Sometimes it's a little pinhole fracture that forces the liquid out like a fire hose, sometimes it's a catastrophic-failure explosion. Or if you're very lucky, it's Simon Jarvis ending up concussed, blood running down his face, while a fit-to-burst yet still unopen can rolls gently down the kerb.

Conkers and marbles year after weary year, school crazes were the very bedrock of playground life. For some inexplicable reason, we broke from tradition, and mouth fresheners were the fashion one year. Unfortunately being approximately 9 or 10, it involved a myriad of schoolchildren waltzing into the local chemists and proclaiming they wished to buy some mouth freshener. To which the response would almost always be - "Are you smoking love - give it up, it will kill you one day" not realising none of us smoked but were too embarrassed to admit it.

We had a teacher who had obviously spent far too much time in the sixties and thought it was a good idea to teach us that meanings of words were subjective. "If you don't MEAN it to have a bad meaning, then it DOESN'T!", he would say.
He went on to say that if we said the word 'fuck', and didn't mean 'intercourse', then the word would be meaningless. Which naturally resulted in our entire fifth grade class saying 'fuck' endlessly.
The best part of it all was the fact that if any other teachers heard us and became upset, we could honestly tell them that Mr. Walter had told us it was OK. This eventually resulted in Mr. Walter taking an extended leave of absence. Fuck.
