Blonde and Blonder (2008)

Two blonde bombshells accidentally witness a mob hit, and are mistaken for assassins by two mafia men working for The Godfather. Thinking the dim-witted duo are the world's best killers-for-hire, the mobsters offer them a huge payout to "take out" Mr. Wong, the head of the Chinese mafia. The clueless cuties happily accept the assignment, embarking on a wild adventure that takes them on the road, all while trying to dodge assorted federal agents and mafia killers.
