The expression "beat like a drumstick" is one I never fully understood when I was younger. Correction: I understood the meaning of it but I completely mistook the reference. To me, a drumstick was a chicken leg battered and fried. I was aware of the real drumstick at the heart of the simile, I just pictured someone beating a drumstick in flour and batter in order to make fried chicken. The reference works both ways and, while I admit the correct one is more descriptive, I'm sort of sad I one day (more recently than I care to admit) realized the real meaning. Sometimes your own view of things is superior to reality. Of course, sometimes it works the other way. The supersonic wind tunnel is awesome, but Desu-San-Desu will ruin it for you.
Disturbing.
