For this prank, the lady of the house is calling in for food to be delivered. When the delivery man arrives—in this case with pizza in hand—she excuses herself. "I have to get the money. I'll be right back."
The rocking horse and book freak this guy out, but nothing compares to his reaction over the zombie painting. He quickly forgets the pack of food in his hand and launches it away from him as he screams in fright.
This delivery guy was also taken in by the flirtatious nature of his customer, but was instantly spooked by the horse and book. By the time the painting changed, he had no trust in what he was seeing at all.
