On Saturday night Manny Pacquiao asserted himself as the "pound for pound" king of boxing, and one of the greatest fighters of all time. After his destruction of Miguel Cotto at the MGM Grand Pacquiao went across the street to the Mandalay Bay and performed an 8 song concert for his fans. On top of his boxing and singing talents Pacquiao is also a movie star, and the embedded trailer is for Pacquiao's starring role as "Wapakman." I don't need to stress how amazing this movie is going to be but if you don't trust me let me see if this changes your mind -- in this trailer Pacquiao fights a giant crab, and apparently wins a gold medal. No seriously. Check it out below.
