A friend of mine studied penguins in Patagonia. When trying to wrangle one to study it, it suffered a heart attack and died. He was destroyed by what had happened.

He kept its ankle band and wore it on a necklace. Despite being just a stamped bit of steel, they’re apparently highly regulated, so it’s rare to have one that’s not on a bird (not exactly sure if him having it was 100% above board).

When he got married, he had it fashioned into his wedding band.

An ankle bracket seems much more comfortable than that choker - we know who’s got the power in that couple.
