The NY tabloids of course,
Now, if you want to give it a miss, I understand but don't want you to miss the high points, it is a gold lame leopard print thong with flames along the waistband belonging to Jason Giambi to which the article refers. Players wear it to break a hitting slump. It is washed in between wearings. And I'm guessing unless Giambi starts hitting real soon, he's going to be the only one wearing it for a time.
Knowing that my own mothership had several ironclad rules, I can only imagine how appalled the mothership of J. Giambi is to read on the front page of the NYDailyNews about her son sharing his panties.
