When I was laughing hysterically at something, my mom would ask me "What's so funny that's making you laugh so much like Hanina". I had no idea who "Hanina" really was, but I thought it was the name of some girl that my parents knew who liked laughing a lot. Later, I found out that she meant "laugh like a hyena", not "Hanina", and a hyena was an animal that laughs.
