It's the real thing all right - suspension.

High school senior Mike Cameron is serving a one-day suspension Thursday for wearing a Pepsi shirt on Coke Day, an event school officials crafted in an attempt to win a $500 contest run by the Coca-Cola Bottling Co.The boy was showing disrespect to guests - the Coke executives who had flown in for the day Friday, Greenbrier High School's principal said.

"I know it sounds bad - `Child suspended for wearing Pepsi shirt on Coke Day,' " principal Gloria Hamilton said. "It really would have been acceptable . . . if it had just been in-house, but we had the regional president here. These students knew we had guests."

Cameron, 19, said he wore the Pepsi logo as a joke. "That's my personality," he said. "I don't like to follow the trend of everyone else."

Hamilton said Cameron also ruined a school picture, a violation that has drawn six-day suspensions in the past. Cameron said he didn't know a picture was planned.

The Coke-themed day was part of an effort to win the contest. The award will go to the school that comes up with the best method of distributing promotional discount cards to students.

Cameron said no one asked him to remove the Pepsi shirt, and he changed into the Coke shirt later in the day.
