Blonde and Blonder (2007)

Synopsis
When two dim-witted blonde bombshells are mistaken for the underworld's most cunning assassins, they are approached with a lucrative contract to take out the head of the Chinese mafia in a globe-trotting, air-headed comedy starring Pamela Anderson and Denise Richards. Two fair-haired beauties have just witnessed a high-profile mob hit, and now the Godfather is convinced that they have what it takes to rub out his most fearsome rival. After accepting a hearty payout and agreeing to carry out the dangerous assignment, the two brainless beauties hit the open road on the adventure of a lifetime. ~ Jason Buchanan, All Movie Guide
