From Ross Clark@21:1/5 to All on Wed Jan 31 14:20:24 2024
Thought up by Megan Emily Scott and Sarah Nicole Miller -- not famous
for anything else AFAIK -- in 1961. "Lanoitan" of course is to be
understood as "ASU".
"They chose this date because, in the American system of dating, 31
January is 1/31 -- which backwards is also 1/31."
(Wait, I'm getting confused....)
Crystal does mention "back-slang" (words like _yob_ and _ripoux_) and mirror-writing (Leonardo da Vinci).
