Little Johnny's preschool class went on a field trip to the fire station. The fireman giving the presentation held up a smoke detector and asked: "Does anyone know what this is?"
Little Johnny's hand shot up and he said: "That's how Mommy knows supper is ready!"
A wife went on a retreat for work. When she returned home, she found a pair of panties in her dresser that did not belong to her. Furious, she questioned her husband. The husband said, "I have no idea where they came from I don't do the laundry!" So, the wife went to the maid and questioned her.
Indignant, the maid replied, "Madam, how should I know? These panties don't belong to me. I don't even wear panties... just ask your husband!"
