Levi Johnston told CBS' Maggie Rodriguez that he has dirt on Sarah Palin that could really damage her but he's not spilling the beans. The father of Palin's grandson did share a joke Palin made about her own son that won't help the former governor's public image. "Coming home from work and she'd be like 'where's my retarded baby?' All of this. It wasn't right," said Johnston.
