Situation: A carcass of a beaver is found in a nearby creek by a group of students. One student asks if it’s a beaver or an otter, for which the teacher doesn’t have an answer but promises to find out.
Student: Never mind. I know it’s an otter. Beavers hang out around dams.
Teacher: Don’t you mean they build dams.
Student: No. They hang around dams. Like Hoover Dam.
