Larynx Puns

Him: "How do you say mushroom in Spanish?"

Me: "With your larynx."

I have a fairly strict rule about only speaking in Spanish in my class, especially when asking "¿Cómo se dice?" or "How do you say?" So, when a student asked me in English, "How do you say 'my birthday' in Spanish?" I responded:

"With my lungs, larynx, lips, tongue, and teeth."

The class blinked for two seconds before groaning in unison. She then asked the question, correctly, en español. But, I think I now understand why cats purr.
