I had the misfortune of seeing this movie because my roommate was watching it. Rarely do I find a film where absolutely none of the characters are worthy of empathy or laughter. The dialogue is cruel more than humorous and the plot is composed of various unpleasant people doing unbelievable things. A "parade of bad" CAN be funny (see: Always Sunny in Philadelphia, The League) but there has to be some sort of wit and human element. Bad Teacher has neither. I recommend this movie to people who love reality television or those who think being mean is the pinnacle of comedy. Anyone with a modicum of taste should look elsewhere for laughs.
