Our physics teacher was always on time to class. She insisted on everyone being on time and finishing their assignments. One morning she was really reprimanding the class on the latest fashion craze going round that we decided to give her a little surprise. The next day, three of the heaviest girls came with maternity bras to class in see through shirts. Everybody was giggling and waiting to see her reaction. As soon as she stepped into the class, she got this funny expression on her face. At first we thought she was about to scream, then to our surprise, she started giving us a lesson on proper choice of undergarments! We could not believe our bad luck, she was totally clueless about our little joke. Maybe she should just stick to physics,she can’t go wrong in that.
