For some reason unknown, refrigerator magnets hit my funny bone.
Maybe because many dogs I've known were stomachs with legs and ate almost anything they could reach, and all of it.
And when you catch them, they look sooooo guilty.
As did my son although he took it twice since he didn't pass the first time around. Obviously you heeded the advice to "approach the subject cautiously."
I would add to that illustrious group the US Physical chemist(s) who decided to use different symbology for basic physical constants once you crossed the "Herring Pond"; i.e., "G" for "F" when discussing Free-energy caused me no end of grief when having to learn Phys Chem from Glasstone rather than UK-based texts in the late 1950s for a BSc in Chemistry.
