Yes, I vaguely remmeber that one day in high school economics class, our teacher, Dr. DePaul, was telling us about his weekend. He had flown in a plane to see Tikal, the ancient pyramid in nearby Guatemala, and upon arriving there, he was hearing Led Zeppelin music playing on a radio, and he soon found that some students from the class were also there at the same time, maybe Raymond and some other guys, and so he was not able to escape from his students, at least not that weekend.
