From the comments on my Tibet post, this seems absolutely brilliant:
A far better approach would be if the athletes themselves engaged in all manner of subversive tactics. I've heard it suggested that the athletes shave their heads in solidarity with Tibetan monks. Can you imagine the apoplectic fits the Chinese would go into if wave after wave of athlete representing various nations entered the arean with shaved heads? What if there was some symbol for Tibet the athletes wore on the medal podium? What if during press conferences, the athletes consciously mentioned the plight of Tibet? The possibilities for mischief are endless.
