One of the lighter stories is called "The Viper." A woman in a high-rise keeps receiving phone calls about a man who calls himself "The Viper" who is slowly coming up the stairs...
Woman: Who are you?!
The Viper: I am the viper. I vish to vash and vipe the vindows.
The hilariously anticlimactic ending to 'The Babysitter.' The titular character is continually being harassed by a lunatic over the phone, and it turns out he was hiding in the house the whole time. Then he comes down the stairs...and is promptly arrested by the police.
