Editor’s note: Do you need something to smile about? Every day, WND selects the best joke offered up by readers and contributors to its Laughlines forum and brings it to you as the WND Joke of the Day. Here is today’s offering:
Little Johnny’s preschool class went on a field trip to the fire station.
The firefighter giving the presentation held up a smoke detector and asked the class: “Does anyone know what this is?”
Johnny’s hand shot up and the firefighter called on him.
“That’s how Mommy knows supper is ready!” said Johnny.
