Two mathematicians met in the university cafeteria. They exchanged hellos and started chatting. It turned out one of them had just prepared a paper and was about to send it out for peer review. He had a draft copy with him and the friend asked to take a look. The friend was nodding to himself as he was reading, but then at one point, he raised his eyebrows and stopped. He asked, "How do you get this from that?" The first mathematician replied, "Oh, it follows trivially." The friend looked surprised, took out a small notepad and a pen from his breast pocket. He scribbled notes and equations for several minutes. Then, he put the notepad and pen back in his pocket, and said, "Yeah, it follows trivially." Marko
