Parents love to teach lessons to their kids, but sometimes they end up learning one of their own.

One clever child found a silent way to end an endless scolding session.

It involved a pinch of salt, a glass of water, and perfect comedic timing.

I made my mom instantly regret it

When I was still a kid, my mom was berating me for almost an hour for doing typical kid stuff — you know, playing outside with friends and not coming quick enough when I heard her yell my name.

She was eating at the time, full-on lecturing me between bites. Then she ordered me to get her some water.

That’s when this kid realized a golden opportunity.

So I went to the kitchen, filled a glass with water, then dumped salt into it.

I stirred it to melt the salt, then transferred the water to another glass and added some more water to fill the glass up again.

Luckily, their mom wasn’t looking too closely.

A closer look would’ve shown the water was slightly cloudy, but my mom didn’t notice because as soon as I got back, she just picked up where she left off while reaching for the glass from my hand — still telling me off as she was about to drink.

Her reaction was worth the wait.

The way she immediately spat out the salty water in a spray on her plate made the even worse talking-to afterward totally worth it.

Now that’s an unforgettable moment.

What did Reddit think?

Some pranks get taken a little too far.

Other times, bullies finally meet their match.

Water isn’t the only drink you can tamper with to exact your revenge.

Some people don’t catch on quite as quickly as others.

The punishment after may have been rough, but at least this kid got to see the priceless expression on their mom’s face.
