Mexican state representatives showed there's always another way to disagree in a democratic society -- just have a few members of your party start a fist fight on the floor of the state house.

Lawmakers in the Mexican state of Nuevo Leon came to blows Tuesday during a bitter debate over the proposed construction of a tunnel.

At least six members of two rival parties scuffled for several minutes before order was restored.

Protesters shouted "yes we can," as the president of the state congress called a recess.
