A Tiger taking a test
 How can this be?

One of my students has this adorable hat that she wears in winter. Whenever I see her wearing it, I always yell in surprise, "Oh my god! A tiger is eating your head!" I’ll pretend that she is slowly being devoured in my class until she takes the hat off.

Then I’ll act surprised. "Did you see the tiger? It was here a minute ago. Where did it go?"

At first when I did this, she got a really confused look on her face. She gave me a look like, "You know this is a hat, right?"

Now she usually plays along, taking off and putting on her hat through out class. Today she had a particularly difficult examination, so she forgot to take it off, which gave me an opportunity to snap this picture.
