Typical comment by an "educator": A Florida schoolgirl was suspended from school for being quiet in class while wearing a pro-gay t-shirt. She was observing a "Day of Silence" on behalf of gays world-wide. The principal suspended her because "Peaceful protests are against school policy."
When you read the definition ("Mudjacking is the process of pumping a water, dirt and cement mixture under a concrete slab in order to lift it. This mixture is called slurry."), it sounds a little close to sewage.
