two-panel hand-drawn cartoon
Panel 1: A mole is emerging from a dirt hole, holding a sign featuring a portrait of the chemist Avogadro. The mole is looking up and exclaiming, "HAPPY MOLE DAY!"
Panel 2: The mole, still holding the sign, looks surprised or corrected when a mole on it's hand says "THANKS! BUT I PREFER TO THINK OF MYSELF AS A BEAUTY SPOT!" The joke references the fact that the word "mole" in chemistry (the unit) is named after Avogadro, but a small dark spot on skin is also called a mole (or beauty mark).
It's a triple whammy folks. A triple whammy!!
A bunch of moles arranged in a hexagon. It's a mole-ecule.
It's MOLE DAY. Happy mole day all. #Chemsky #chemistry #moleday #realtimechem
