Saw that a couple of days ago and though, "If you're so dedicated to your cause, why don't you just get up and move back to your previous spot while your friends are being moved?"
Hahahah that is awesome. Reminds me of some protestor who clued himself to a table on a TV talk show, so they just lifted and moved the table off the set.
No matter how well you plan your dignified and stately protest where you recite a communist monologue, pour soup over your head, and superglue your hand to the building, something embarrassing might still happen.
