Skits about blood

In my biology classes, I decided to exploit the Thai student's love of theatrics and assign them a skit. They were supposed to act out human blood, so we had fights between white blood cells and bacteria, sometimes with prop guns and knives. Almost everyone wore some kind of hat to identify who they were, and it was a generally good time.

I was amazed at how much the others, sometimes even kids within the performing group, were talking during the show. I tried to explain that it's rude, but I remembered how Thai's deal with the issue of not being able to hear a performer. They just find the biggest most obnoxious speakers they can find and blast out all other noise. Some of my coworkers do this in their classes, but I think it kind of defeats the purpose.
