Flashing your teacher - Thats Embarrassing!!

one saturday i was walking down the street with my friends to go somewhere. As a joke, they dared me to flash the next car i saw, well i kept saying no until i finally flashed a car. low and behold it turns out to be one of my pe teacher coming at me and a police car the opposite way. Well, when we went to school on monday, my pe teacher (NOT the one i flashed) told me that when i walk down the street, dont do anything that could get me arrested for In other words, he told like ALL the other teachers!!
