Back in August and September, there was a discussion here about the distribution of colors in packages of M&M candies. Recently, however, the abbreviation "M&M" has been used to refer to the Moore & McCabe statistics text. It took me several such references over a few days to figure this out! Reminds me of a college math professor I had in my freshman year who frequently used the abbreviations LHS and RHS without ever saying what he meant by them. I dutifully copied them into my notes, but was too embarrassed to admit my ignorance by asking what they stood for. It was several weeks before he actually said "Left-Hand Side" as he wrote "LHS" and I went from darkness into light!
