Funny Chinese Slogans

Regarding criminals:
- 在河南的國道上看見的： "搶劫警車是違法的!!"
(Illegal to rob (steal?) police car)
- 在山東看到的標語："光纖沒銅，偷也沒用"
(Optical fiber does not contain copper. No use to steal.)
- 有一路口有一標語，上書： "投案自首是犯罪" ，大吃一驚之餘往下看...還有： "份子的唯一出路"
(Ah... too difficult to translate....)

Regarding birth control:
- 雲南楚雄某農村標語: "一人超生，全村結紮!"
(One extra baby, whole village to vasectomize!)
- 北京某遠郊縣： "少生孩子多種樹，少養孩子多養豬！"
(Give fewer birth, grow more trees. Feed fewer child, farm more pigs!)

Amazing...
