Dripping Disturbance

The faucets are dripping in old New York city
The faucets are dripping and oh, what a pity,
The reservoir's drying because it's supplying
The faucets that drip in New York.

—Malvina Edwards, "The Faucets Are Dripping"

So, the night comes rolling in and it's time to go to bed. You brush your teeth, put on your pajamas, and get all snuggled nice and warm in bed. You then close your eyes and begin to drop off to sleep...

You suddenly hear a loud dripping sound from the bathroom and go to see what it is. You see that the faucet is dripping because you apparently didn't turn it off all the way. Once you turn off the faucet, you go back to bed, but as you get back in the bed, the faucet starts dripping again, even when you turned it off! One of the things that can result in a Do It Yourself Plumbing Project.

This is a Comedy trope that can be Played for Laughs or Rule of Funny in any form of media. Expect to see it in Western Animation. Compare Fly Crazy for a situation similar in execution.
