When the Mets signed Kris Benson for $22.5 million over three years last month, they might not have fully factored in the Anna Benson factor.*On Tuesday's Howard Stern Show, Kris' wife Anna made it clear that she would get more than even with her husband if he*slept with*a baseball groupie. "I told him -- because that's the biggest thing in athletics, they cheat all the time -- I told him, cheat on me all you want," she said. "If you get caught, I'm going to screw everybody on your entire team, coaches, trainers, players. I would do everybody on his whole team." Anna also took credit for his contract negotiations. Nancy Seaver, she's not.
