A couple woke up to banging on their door.
After getting his gun from the drawer, just in case, the man went and opened the door to find his neighbors there. "DON'T USE THE WATER, IT'S POISONED!", they said. He assured them that he and his wife won't drink water and the neighbors left.
He went back to his bedroom and his wife asked him, "What happened, sweetheart?", she said. He replied "Nothing, honey! Just go drink water and let's go back to sleep."
