Metta World Peace has no interest in extending a hand to James Harden when the Lakers open their Western Conference semifinals series against the Thunder.

"I don't shake substitutes' hands," World Peace said after the Lakers' 96-87 Game 7 victory over the Nuggets on Saturday. "My concern is executing the coaches' game plan and that's what my concern is."

World Peace said the entire Thunder team has a habit of forgoing the usual pregrame handshake or fist pound.

"I shake everybody's hand before the game, but Oklahoma City, they don't shake hands," World Peace said. "Only some of them, but I don't think they really shake hands before the game.Kendrick Perkins and now (Russell) Westbrookdon't shake hands either. (Russell) used to shake hands, but now he don't shake hands anymore."
