I listed it in the other post. I rigged a sink hose to spray someone when they turned the water on.

we had an iconic one
That's exactly the one I thought of when I read the title Thanks for sharing.
I live in sheltred accommodation last year I made and distributed a poster about a rabbit that had gone missing whose Name was Tom Fullery I got the rabbit picture off the net and posted MISSING! at the top _ I was surprised at how many people thought it was real.
Many years ago I was a hospital wide courier and one unit clerk (we were old friends) used to pick on me telling me I never brought her any flowers, just paper work. So one april first I found some dead daffodills, stems only-the flowers had fallen off, and put them into a styrofoam cup. I walked up to her desk in the nurses station-it was full of nurses, doctors, and PAs- and plunked the cup in front of her and said "Here's your flowers". It brought the house down. We laughed about it for years.
I'm a high school math teacher. One year, after we had just finished doing all of the standardized tests for the year (which take about a week), I announced to mu classes that there was a mistake in the tests, and we had to do them all over again.
I had them going all day believing this.
Many years ago, I worked in trade marketing for a company that made a variety of luxury scented products including potpourri, candles, lotions, and soaps. I was busy in the lab putting together samples for a trade show and my arms were covered in hives (allergic to something in the potpourri).
One of my coworkers had set out samples of a new lotion fragrance for us to try. She didn't know what I was doing that day, different department.
So around lunchtime, I wandered into her cubicle, showed off my arms and said, "So, about that lotion..."
She FREAKED.
April Fool's Day.
In Haiti, the usual way to do "poisson d'avril" (April Fool's Day) is to "voyer" (send) people on fake errands.
One kid, Derelise, sent a friend almost all the way to Cap Haitian to see someone who supposedly wanted to see him. When the guy returned on his bike, smiling sheepishly, he admitted that he'd already sent his own cousin to another town on a fake pretext, so should have known better.
