Test question in a Let's Go Three class of mine:
Your sister is dirty. Where's she going? How is she going there?

Bill's (a student) answer -- She go pot dong.

He handed me his paper and when I got to that question, I had to try to control my own laughing. It took me a while to figure out that he must have thought I had asked 'what' and not where. As for the 'pot the dong' part of things I think he was trying to say something about putting dung somewhere.

What I think he meant: She goes to the bathroom to poop.

What I was looking for: She's going to the sauna. She walking there.
