Final answer:
Mark's practical joke on Luke involving a fake robbery and a candy gun could be seen as intentional infliction of emotional distress, as it was intentional, extreme, and caused severe emotional distress in a sensitive setting.
Step-by-step explanation:
Mark's act of playing a practical joke on Luke by pretending to rob him with a candy bar shaped like a gun and threatening his life could potentially be considered an act of intentional infliction of emotional distress (IIED). The legal elements that typically need to be established for IIED are: the defendant acted intentionally or recklessly; the defendant's conduct was extreme and outrageous; the conduct caused the plaintiff emotional distress; and the emotional distress was severe. In this situation, Mark intentionally caused Luke fear and distress by simulating a dangerous and life-threatening situation inside a bank, despite the fact that the handgun was made of candy. The intensity of Luke's fear during the incident suggests that the emotional distress could be considered severe.
Furthermore, Mark's actions within a highly sensitive environment, such as a bank, and the realistic threat with a seemingly deadly weapon, make his conduct extreme and outrageous, fitting within the definition of IIED. Drawing from the provided examples, Mark's behavior reflects a pattern of highly inappropriate and reckless actions in various scenarios, reinforcing the potential for liability under tort law.
