Here’s a pretty good retargeting joke we found on Reddit:

A coworker was complaining that his spoons were slowly disappearing from the lunch room. He had brought six to work and he was down to two.

Everyone else at the office hatched this plan: every time someone sent him an email, at the bottom, in white text (i.e. invisible unless highlighted), everyone would write “SPOON SPOON SPOON SPOON SPOON SPOON SPOON”.

We all did this for several weeks (he had a gmail account). That’s when he started losing his mind: every website he visited had ads for spoons and flatware! He thought Google was reading his mind.
