joke: Stress Relief.
It was late in the evening and I was studying in the university library's reading room. It was in the middle of final exams, so the library was a hectic place with students milling around everywhere. I was sitting at my desk with my pile of books and felt the need for a nap before I continued with my work. I wasn't asleep long before I was awakened by laughter. To my surprise, everyone who was laughing was also looking at me. I looked around the room, silently pleading for answers, when someone next to me leaned over and whispered, "You were farting in your sleep."
