It was obviously meant as a funny joke ;-)

But on a more serious note. Humans "prompt" each other all the time. Especially in a Boss->Employee relation.

Defintion of "to prompt":

1. To cause or inspire: To make something happen or motivate someone to take action. For example, a loud noise can prompt you to look outside.

2. To assist or cue: To help an actor or speaker remember forgotten lines or words.
