Deer
A canopy and a helicopter are being compared by a deer. The deer is standing very still (as deer do) and looking very slowly between the empty canopy and the helicopter sitting next to it.

You walk forward, about to call out to the deer, when a car (か) suddenly appears out of no where and runs the deer over! Was this all just a trap set up to murder the deer?!
