April fools jokes with personal relationship issues aren't such a good idea, I think.
When I was younger and foolisher, I did two at work a couple years apart.
1st, on a really big multi-month development project with a very hard non-moveable deadline of May 1, after we'd been working on it for a few months already, I wrote a long memo to my boss explaining that the work directory had accidentally been deleted, since it was new for this project only we'd forgotten to add it to the backup scripts in the first place, so it was all gone. . . and no way to redo the work again to meet the deadline. I went on and on for, well, 10 paragraphs. The first, capitalized, letter of each para spelled out APRIL FOOLS. She read it with me sitting at her desk looking grim. She turned gray and started sweating. She asked me questions about how this could happen. After a bit I finally told her that maybe there was one way out. . .and suggested she look at the first letter of each para. . .
She yelled, threw things at me, then ran off with it to pull the same trick on other Vice Presidents. . . But then we had a really good relationship anyway, or I wouldn't have tried such a thing.
2nd, and worse one, still feel bad about. Changed the logon of an IT coworker/project team leader, to start an initial job at logon that said "Deleting all production files. Would you like to Continue (Y/N)?" Of course it didn't matter what you entered. . . it went off for 30 lines of "DELETE" "DELETE" "DELETE", etc. At the end of which, it looped back and asked the question again. . .she's freaking, I'm yelling "What did you do? What did you do? My god, answer 'N' this time!" Etc.
That one was mean. She wasn't too stable a person and I think I damn near gave her a nervous breakdown. The only good thing was she was so relieved to find out it was a joke that she didn't complain to management. . .
