XKCD comic, described below.
Transcript

[Cueball and White Hat are standing and talking, White Hat with hand on his chin.]

White Hat: Sounds bad. Let's offer a bonus to anyone who identifies a metric that has become a target.

(Sourced from explainxkcd.com)

Title text:[later] I'm pleased to report we're now identifying and replacing hundreds of outdated metrics per hour.
