What is your most memorable childhood prank

[Dorothy V]

16. Oh Lordy! My friend, a tarantula, and me!

It was the 5th grade, and the school was in the Mojave Desert. October, overcast skies, noon recess. Friend and I spot a tarantula out on the playground, no doubt a male looking for a lady tarantula. Now, I am scared of spiders, much less tarantulas, but my buddy got a gleam in her eye, nudged the spider into her lunchbox, and the plot was hatched! There was a boy who had been bedeviling us, and with me as lookout, she slipped into our classroom and put the tarantula in his desk!
Class starts, the boy opens his desk, and promptly lets out a scream that was surely heard plumb to Vegas! The teacher runs up, takes one look, and her scream was no doubt heard from Berdoo to Albuquerque! Pandemonium! Screams and yells and the class bolting for the door! The school custodian had to come and de-tarantula the kid's desk.
Unfortunately my buddy and I gave ourselves away by laughing our fool heads off. Swats in the office and then more trouble at home. It was worth it though!
That boy never bothered us again.
