A few years ago, a mother and father decided they needed a break, so they wanted to head out for a night on the town.  So they called their most trusted babysitter. When the babysitter arrived, the two children were already fast asleep in bed. So the babysitter just got to sit around and make sure everything was okay with the children.      

Later at night, the babysitter got bored and went to watch tv but she couldn't watch it downstairs because they didnt have cable downstairs (the parents didn't want the children watching too much garbage). So she called them and asked them if she could watch cable in the parents' room. Of course the parents said it was ok, but the babysitter had one final request.

She asked if she could cover up the clown satue in their bedroom with a blanket or cloth, because it made her nervous. The phoneline was silent for a moment, (and the father who was talking to the babysitter at the time) said....take the children and get out of the house....we'll call the police...we don't have a clown statue... the children and the babysitter got murdered by the clown.      

It turned out to be that the clown was a killer that escaped from jail.
