Detective (reading the football helmet, which has a decapitated head in it): Sagebrush Valley High School. The Cobras.
Nick: Looks like he could still be in high school. Boy, football's gotten a lot more brutal since my playin' days.
Detective: Well, where's the rest of him? Still out on the field?
Nick: Well, there are no high school football fields around here. What do you think, Grissom?
Grissom: Ichabod was horror struck on perceiving that he was headless.
