Some one already posted this but its the only story i could think of right now
One day a teenager was babysitting. She put the kids away, and went down stairs to watch TV until their parents came back. She was watching a movie when the phone rang, she picked it up and in a deep voice a man said,
"Have you checked the kids?"
"Who is this?" she asked not too scared thinking her friend was just trying to freak her out. Click, the sound of him hanging up. About an hour later..
"Have you checked the kids?"
"This isnt funny" she said angry. Click, the phone turning off. Again, an hour later..
"Have you checked the kids?"
"Im calling the cops" she said, by now she was freaking out. So thats what she did, call the cops
"This guy keeps calling and asking if I've checked the kids"
" 'Mam, get out of the house, NOW, the calls are coming from upstairs!" The 911 registirer said, but the girl didn't listen. She ran upstairs and found the kids, dead. She freaked out and ran outside. Years later she still has nightmares. But one day her and her husband decide to got out to dinner, so she got a baby sitter, and went to dinner. About half way through, she got a phone call "Oh must be the baby sitter asking something" she thought. But when she opened up the phone she heard
"Have you checked the kids?" So freaked out she practically yelled
"We need to go, NOW" and she ran outside and sped home. The babysitter, who thought she was crazy, said
"The kids are fine" and when she ran upstairs they were. She was traumatized so she got in the shower, to kinda cool off, then headed to bed. Her husband was snoring,she thought "Ugh great, so I'm not gonna get ANY sleep tonight and hes snoring his head off" so she shook him up. And he replied
"Have you checked the kids...?"
I dunno if its true but theres a movie about it that my BFF was watching when she was in college and she was still freaked out
