Since April Fools Day is coming up, here's a great idea for a prank: set up a creepy mannequin in your hallway for one of your family members to find when they come home from work. If they're anything like this chick, they'll flip out, run to the neighbor's house and said neighbor will call 911 reporting a break in. April Fools!
See, it pays off to spend time watching Rescue 911. This show gives great tips!
