Here is 50 Cent representing and (briefly) spitting at the Queens outdoor party he finally got to hold on Saturday. Fitty originally wanted to do this “40 Day” at his old P.S. 40, in August, but couldn’t get permits, which some people believed was the fault of Mayor Bloomberg, who thought the rapper’s name is 50 Cents. The artist announced himself “full of positive energy” and added, “I’m on my best muthafuckin’ behavior. Another day, I’ll be on some bullshit.” 50 and G-Unit each did sets and the event passed without untoward incident.
