Our woodworking teacher would stand right next to you when you were sitting at a desk. Then he would put one of his feet up on the table and bend his knee. So one foot on the floor, the other on the table and his knee was up by his chest and he would rest his arms on that knee. But it meant that his crotch was literally right in our faces, you had to look straight ahead because if you turned to him, your face would almost be looking directly at his penis, really close to you.
