Cleaning my hand print off of a mirror. Don't high-five your reflection. Just nod or wink.

In this joke, Cook riffs on the small, private rituals of self-encouragement—psyching yourself up in front of a bathroom mirror—then undercuts them with a practical, slightly absurd consequence. A high-five with your reflection is framed as overconfident and performative, and it literally leaves evidence: a greasy handprint you then have to clean. The punchline proposes a more understated alternative (“nod or wink”), suggesting that modest self-affirmation is both cooler and less messy. The humor comes from treating a fleeting motivational gesture as if it were a social faux pas with housekeeping repercussions.
