Easy Tiger!

I have a student called Tiger. He's a bit of a character - I had to confiscate a book from him last week, right after going through "The Rules" (No mobile phones; No mp3 players; No books; No homework), which I now do at the beginning of every single lesson - but he's funny with it so it's not too bad. But I just love being able to say "Tiger, no!" or "stop that, Tiger!" when he's talking in class.
