The biology teacher at my high school was an English lady. After she told an Irish joke in class, I bought a St. Patrick's day card that proclaimed the recipient an honorary Irishman, because she had "Courage, wit, humor and just a bit of blarney". (She had none of these, but never mind.) The entire class signed it.

A few weeks later, when we had the new kitten neutered, she asked for his testicles. I brought them to her gift wrapped, with a card from the kitten.
