A park ranger is warning some hikers about bears. "Brown bears are usually harmless," he says. "They avoid contact with humans, so we suggest you attach small bells to your backpacks and give the bears time to get out of your way. However, grizzly bears are extremely dangerous. If you see any grizzly-bear droppings, leave the area immediately."
"How do we know whether they're grizzly-bear droppings?" asks a hiker.
"Easy," replies the ranger. "They're full of small bells."
