A lecture joke

I was a joke today. During the Chemistry lecture in the first 2 periods, Justin and i made a fool of ourselves. In the midst of the lecture, the lecturer suddenly turned to our direction and said, "I have observed you two for a long time. You all have been talking a lot and turning to your friends behind as well. Please get out of the LT now." At that time, i was feeling very tired. I couldn't really sleep the previous night because i kept thinking about how the track dinner went. Then, i took a glance behind and the lecturer instantly said, "Yes you two, don't need to turn around." I can't be bothered to argue with the lecturer or check whether it is us who talked. So i put down my stuffs and left the LT with Justin following behind me. We went to the canteen and planned to stay there till the end of the lecture. The time will be well spent discussing soccer tactics for our matches today. Then, Jared suddenly appeared and told us that it actually wasn't us. It was Benjamin and Eugene. By then, Benjamin and Eugene have also been sent out of the LT. Then, Justin and i walked back into the LT and people were laughing. The lecturer said, "... you two must be guilty conscious." Apparently, when we left the LT, the lecturer continued to scold people for talking. My friends thought that she might be warning the students as a whole. The lecturer then said, "What's the names of the two of you?" People in the LT found it a bit weird because Justin and i had already left the LT. Then, she said, "I don't want to make it so explicit but the guy with the red spectacles and the guy beside you, please get out now!" The people in the LT started to laugh. Poor Subra, he had to sit alone in the LT for a short while as the 2 people on the left and on the right side of him had left the LT. It was definitely a moment of madness and i willingly sent myself out of the LT. Nevertheless, it "brightened" my spirit for the rest of the day from the disaster the previous day.
