-- A high school lunch period was disrupted Monday by a greased, naked student who ran around screaming and flailing his arms until police twice used a stun gun on him, authorities said.

Taylor Killian, 18, had rubbed his body with grapeseed oil to keep from being caught, and got up after the first time he was shocked to continue running toward a group of frightened students huddled in a corner at Westerville North High School, Lt. Jeff Gaylor said.

"That prank went a little farther than he intended, I guess," Gaylor said.
