Pretend to be going out for the evening and hire a babysitter (a local teenage girl, etc). Tell her that your child is asleep upstairs and do not disturb him or her. Call about an hour after you left and ask babysitter to check on your child.
When the babysitter goes upstairs, and there is no child in bed, they freak out!
When the babysitter gets back to the phone, scream, “What the hell happened to my child?”
This was a guest Prank Post from Rose W.
Here is another babysitter prank that was done on Scare Tactics and is my favorite prank from the show.
