As for successful April Fools jokes, I once placed a sonalert module connected to a small Solar pannel atop our refrigerator. When my wife came in to the kitchen that morning and switched on the light, she could hear it as well as see it. The light is a fluorescent tube fixture so the sonalert had a nice 120-HZ rasp to it, kind of a RRRRR sound. She turned the light off immediately and then back on again and, of course, the sound resumed. She said some mild expletive about how the light is buzzing. I reached up and hauled down the Solar pannel and sonalert module while saying, "April fools." She wasn't terribly amused.
