If you've been reading since I started, you'll remember that my students go nuts for role-plays and skits. It is the most they care about English all semester. This time around, I really encouraged them to be creative and funny, and to use props and costumes.
I got a lot of top-notch skits with details about the Alternative Medicine (our current unit) they were supposed to have researched and then this:
Student 1: Hi, How are you?
Student 2: I'm very sad. I cannot eat, cannot sleep
1: Why that?
2: Because I fall in love with one woman
1: What is her name?
1: Really, is she beautiful?
2: She is so beauty, tall slim smart perfect every thing
1: Oh! So you're hurt a lot
1: Okay you must try aromatherapy. It so good for you
... this with straight faces (to their credit) - can't say the same for myself (or the rest of the class)
I gave them 5/5 for performance/creativity (aka balls)
