Stu manages to survive his ordeal while he identifies the caller as the man who tried to deliver him a pizza in the beginning of the film. It turns out the caller is still alive and he pays Stu a visit while he is in the ambulance. He lets him live but promises he'll be back if Stu loses his new found honesty. And then a phone rings.

The Caller: Deception can't go unrewarded.
Trivia: The big speech from "Couldn't you find anyone worse? A child molester..." to the bit where Stu is shot was filmed in one take. Colin Farrel did everything and surprised himself and the crew. When he hit the floor, the crew (and the extras) had to contain their applause until the cameras stopped rolling.
Question: Are the pizza delivery guy and The Caller two different characters? I was always under the impression that they were one and the same.
Answer: The pizza man is intended by the Caller to be a decoy so he can get away. The Caller sends the pizza man to the phone booth so that Stu will identify him later in the apartment, giving the police a convenient answer to the mystery while the real Caller escapes. In fact, at the end of the movie, the Caller comes to visit Stu - obviously he's not the dead pizza delivery man.
