Via the inimitable Dave Weigel, parliamentary procedure gets exciting in Wisconsin.
A few notes:
1. Some Americans are going to consider this the collapse of civilization, but this is pretty tame stuff by international standards.
2. If you're wearing orange shirts in the chamber as a show of solidarity, don't expect the other side to play nice.
3. Liked the guy who shouted "we love you anyways."
4. Never be the last person chanting.
Added: Weigel's diary of the scene inside the Capitol is worth a gander, too.
