A naked man was taken to the hospital after he body slams a pick up truck during a bizarre incident in Oregon. 38-year-old Amos McLean wound up being struck by the travel trailer as the driver tried to get away.

Police tell KVAL that they have no explanation yet for McLean's behavior Sunday night. Witnesses told police McLean stood naked in the center of Highway 20, shouting and waving tree branches.

He then entered a neighbor's vehicle, removed a box of mail and moved to the center of the westbound lane, where he sat down, police said.

As vehicles approached him and stopped, McLean got up and approached a Ford F250 pickup pulling a travel trailer driven by a 57-year-old Salem man.

Witnesses told police McClean slammed his body into the side of the pickup and then punched the rig. As Simpson pulled away, the travel trailer hit McLean, knocking him to the ground, police said.
