I also pulled one on my poor great-aunt (my sister and I); they sold this gag gift in Spencers which was a speaker activated by an air bulb-someone sits down, and a man’s voice comes on saying, “Hey lady I’m working down here!” followed by several seconds of simulated farts. She very quickly stepped out of the bathroom with the most mortified expression on her face that I’ve seen on anyone, ever. She was good-natured about it later (my sister and I were quite the monsters, esp. when we did shit like that to each other a la Wednesday and Pugsley).
If you have a Water Pik and your bathroom light has an outlet on the base, then turn off the light at the wall, plug the Water Pik into the fixture and point the Water Pik at the doorway.
Kill them all and move to another state. It has done wonders for me.
Good one and less messy…
If you use bar soap, take the bar when dry, and cover it all over with clear nail polish. Hand washer will grab the soap, and try to lather…it took my husband quite a while to realize he had been pranked.
I got that from Martha Stewart, of all people!
