April Fools' Showers
This prank is best to pull on someone who can take a joke...or rather, a soak.
To do the prank, your kitchen sink must have a sprayer hose. Without pulling the hose out, put a rubber band tightly around the handle of the sprayer so it’s held down in the “on” position. Make sure it’s pointed in the direction of a person who is standing at the sink.
Then wait for your victim to come in and turn on the water. The water will come through the sprayer instead of the faucet and deliver a nice, cool, April Fools' shower.
