Cadets in training at the Indiana University Police Academy must endure a multitude of rigorous exercises.
Perhaps the hardest? The "chicken drill," in which the trainees must keep a straight face as a rubber chicken is waved in front of their faces.
Keep a straight face, and you pass.
Crack up, and you drop to the ground for push-ups.
The exercise is designed to test resolve and composure.
Could you pass?
