I've never found word origins very interesting. Every once in a while, I'll wonder how we ended up with a word like "shampoo," so I'll look it up to see that it comes from a Hindi word meaning "to massage."
But for the most part, in those moments when I'm feeling both intellectually curious and energetic enough to do something about it, I'd much rather learn about chemistry or geology or modern French or credit default swaps than the points A, B, and C that one of our words passed through. (It probably has to do with my aversion to history and linear time in general.)
Today, however, I make an exception. It's a passage I came across in "The Omnivore's Dilemma" in a chapter about corn.
"The shelled cobs were burned for heat and stacked by the privy as a rough substitute for toilet paper. (Hence the American slang term "corn hole.")
Now that's etymology.
