One two Freddy's coming for you

Three four Better lock your door

Five six Better grab your Crucifix

Seven eight gonna stay up late

Nine ten Never Sleep again!

The song is sung by three girls jumping rope, one of them being Freddy's daughter Maggie. It pretty much sums up what to do if Freddy decides you would be a good target. Lock your door, grab your crucifix, stay up late, never sleep again. By doing all of those things, you have a chance of surviving Freddy's rage.
