Ha! I took a Hungarian class with my daughter a couple of years ago; I think she was 8, which is why she needed me to sit in with her, given it was a college class at IU. (I should explain that her mother is Hungarian, and so this was more in the way of language practice and grammar instruction, not that my daughter is a super-genius. Although, of course, she is.)

Anyway, one of the dialog exercises was to talk about hobbies, and one of the hobbies was record collections, with a picture. She had absolutely no idea what the picture was supposed to be, until I explained to her that they were like CDs. The other students in the class exploded with laughter.
