I agree By JulieP

I remember having a science teacher in high school that let it slip out to her problem class that she was terrified of snakes. When she opened her desk drawer the next day, there was a garter snake! Not missing a beat, and teriified to death, she picked the snake up, said "Cool, another class pet to perform late night experiments on" and evilly laughed while placing the snake in a glass container. Needless to say, when she returned to her room after lunch the snake was gone and she had no more problems from her problem class.

When they try to get your goat, use this phrase:
Yeah, that's a good one. You know, I tried that when I was your age, too, only difference, it worked when I did it. And walk off. It even worked with third graders, and students that I subbed in jr and sr high.
