Formaldehyde Memes

Chemistry wordplay at its finest! Formaldehyde is that pungent chemical used to preserve specimens (and nightmares from biology class). The joke brilliantly plays on "formal" vs "casual" and sneaks in a Jekyll/Hyde reference because, let's face it, chemicals have personalities too. Next time you're at a chemistry party (yes, they exist and they're exactly as wild as you imagine), drop this gem and watch as everyone simultaneously groans and updates their periodic table of puns.
