Every night, a man takes a shot of whiskey before bed.
After years of this routine, his wife decides enough is enough. To make her point, she sets up a little experiment at the kitchen table: two shot glasses—one filled with water, the other with whiskey—and a bait box of worms.
“Watch this,” she says.
She drops a worm into the glass of water. It wriggles around, alive and well.
Then she drops a worm into the whiskey. It instantly shrivels up and dies.
Triumphantly, she asks, “So, what does that tell you?”
He pauses, nods thoughtfully, and says:
“If I drink whiskey, I won’t get worms!”
