Jon Gosselin -- Target Practice
There's one essential rule of divorce warfare ... know your enemy -- So Jon Gosselin did some bonin' up about Kate in the bargain bin at Target.
Jon flipped through ex-wife Kate Gosselin's memoir "I Just Want You To Know: Letters To My Kids On Love, Faith, and Family" yesterday at a mega-store in Pennsylvania.
He, like everybody else, didn't actually buy a copy.
