I spent three hours debugging code while my coworker hummed the same eight bars of a song on repeat—apparently a promotional jingle for a yogurt brand neither of us uses. When I finally snapped and asked him to stop, he looked genuinely hurt and said he didn't even realize he was doing it. So now the yogurt owns two of us: he's stuck humming it unconsciously, and I'm stuck pretending I'm not fantasizing about unplugging his desk fan and replacing it with a metronome set to 40 BPM, just to see how long it takes him to sync up with it instead.
