Classmates teased all teachers of every class.  In Korea, teachers are teaching students in the same classroom. Therefore students can tease teachers easily.  Today we teased some teachers. We told our math teacher: "Teacher!Please, Up ! skirt".  She was confused but we were pleasant. Actually we had deposited the uniform skirt at a closet by near the large television. In another words, teacher was confused while thinking of that skirt. PS.Look at the dairy before.
