During my cooking class, the teacher took us out into her garden to show us some typical plants and herbs. She pointed at her pepper plant, thick with bright red chiles that looked like christmas lights, and said, "In English you call these 'bird's eye' chiles. Here in Thailand we call them 'mowshi'."
"Mowshi,' we all repeated faithfully, trying the form the sounds right.
She gave us a funny little look and said, "Yeah, mowshi because it looks like shi(t) of mouse."
