Blonde and Blonder (2008)

Dee and Dawn are two dim-witted, pink-clad blonde ladies who meet by accident and try to make a living with their dull lives until a series of circumstances ensue when they unwittingly take jobs at a local strip club. They are mistaken for two deadly female brunette assassins, known only as the Cat and the Kit, who are hired to kill the club owner who is a mobster in a witness protection program. With two persistent but inept FBI agents on their tails, ditzy Dee and Dawn try to stay one step ahead of the law--and also try to figure out what is really going on.
