palindr-o-mania

i think i might be nerding myself out, but i think this is neat.

once, i read an Encyclopaedia Brown short story in which he knew where the key was because it was under a word that was also a palindrome. the thing is, he found it under an eraser. and it has perplexed me for years just how exactly eraser is a palindrome (the same word or phrase forwards and backwards). it keeps me up at night.

another question: why didn't they chose a word for palimdrome that was actually a palindrome?
