One of those, "Yep, I'm definitely living in Japan" moments...

Me (pointing at a small cooler on the floor in front of a student): "What's that?"
Student: "It's a pig's tongue. For dinner tonight."

Yep. He works as a meat inspector and apparently, the tongue was a "gift" from his co-workers.
Maybe his co-workers don't like him very much. Or maybe I'm just a foreigner living in Japan.
