Riddle: Professor Hunter, a former world traveler and recently retired community college teacher, is now able to pursue his favorite hobby in the comfort of his own home. Several diplomas, certificates, and a license to practice his hobby adorn his study where he continues to engage in his favorite pastime, which also happens to be the subject he taught part-time at the community college. He told me of a nightmare he had last week after he fell asleep in his study. The professor said he dreamed he was on a hunting expedition in an African jungle, far from any civilization. In his nightmare, he found himself alone, without any weapons, and was suddenly surrounded by a lion, a hippopotamus, a leopard, a cheetah, and a ferocious cape buffalo. They were just closing in for the kill when he suddenly awoke from his dream. But was it a dream? Professor Hunter said he nearly had a heart attack when he looked around the room, and realized the dream was real after all! What was the professor's hobby, and why was he so frightened when he awoke from his dream?
Answer: Professor Hunter was a world traveler as well as a big game hunter. He studied the art of taxidermy, got his license, and taught this favorite hobby of his at the community college for many years. He decorated his study with the heads of several big game animals he had bagged while hunting in Africa. He gave himself a genuine scare when he awakened from his dream to see the heads of the very animals of which he had just dreamt.
