* Fictional Character: Rob Schneider's character is a fictional creation. While he does go on a rampage, his actions are purely for comedic effect and don't reflect any real-life individuals.
* No Specific Names: The movie doesn't provide any specific names for the "robs" he eliminates. The humor is based on the absurdity of his actions and the exaggerated reactions of the other characters.
It's best to remember that the movie is a comedy, and the "slaughters" are part of a silly and over-the-top joke.
