Watch an episode or two of on patrol. Will really get your juices flowing. Drivers license? O comprende. This your car? No comprende. You been drinking cervesa? No comprende. The only positive point is they are generally not combative.
I have noticed that on the show and was surprised to see soooo many illegals in South Carolina. A lot of the illegals they stop claim to only speak Portuguese. Brazilians? Wherever they are from they ALL need to be sent back home.
