The perfect illustration of biochemists' daily cognitive dissonance! Patrick claims biochemists don't work with harmful chemicals, while SpongeBob is literally surrounded by a rogues' gallery of lab nightmares. Beta-mercaptoethanol (the rotten egg smell that follows you home), ethidium bromide (casually staining DNA and possibly your DNA too), cesium chloride (heavy metal toxicity, anyone?), imidazole (irritating in more ways than one), and sodium azide (the compound that's one accident away from becoming explosive nitrogen gas). But the punchline? SpongeBob absolutely losing it over 70% ethanol being "carcinogenic" – the same stuff we've been bathing our lab equipment in for decades. It's like being terrified of a puppy after wrestling alligators all day. Every biochemist is nodding furiously at this while pipetting something questionable without gloves.
