Today in delightful cultural crossover: über-icon Manny Pacquiao will join forces with über-icon-in-his-own-mind Rick Ross before he fights über-39-year-old Sugar "Shane" Mosley, who is but a pawn in this sick, sick game, next Saturday.

Word on the street is that this is Pacquiao's attempt to send a message to Floyd Mayweather, who often travels with 50 Cent. You know about beef between the fighters. The rappers also have plenty of beef.

The above video includes Pacquiao's right-hand man, Buboy Fernandez, repping Ross's Maybach Music Group. Ah, the apotheosis of the sweet science.
