The story goes that when the famous Greek painter Apellis made a full-body painting of Alexander the Great and showed it to the audience, a shoemaker approached him and made some comments about the rendering of the sandals of the great warrior. The painter promptly acknowledged the error and with a stroke of his brush corrected it. But after a while the same man started to comment about the robe of Alexander and the painter cut him short by saying, "Stick to the sandals, my valuable friend".

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
