My teacher is very unfair.  He gave better grades to stupid students because he liked them.  How can I make his life miserable?

You could try telling him that his grading scheme isn't fair and you'd like to see him apply a stricter standard to all the students. This could lead to a constructive conversation about the evaluation criteria. Alternatively, if the teacher is especially sensitive, you could use his students' work as the basis for humorous jokes and stories to let him know that you think his grading practices are unequal.
