The Heat got help from some politicians Wednesday night in debuting a new public service announcement aimed at keeping South Florida litter-free.

Miami Mayor Manny Diaz and Miami-Dade County Commissioner Dennis Moss were on hand for the debut of the county's “SLAMIT JAMIT STUFFIT” ad, which was shown during halftime of the Heat-Knicks game. The campaign, which shows Heat coach Pat Riley; players including Dwyane Wade and Udonis Haslem; and a dancer exiting a bus and shooting bottles, foil and other bits of garbage into a trash can, is being accompanied by in-arena anti-litter messages and contests.

The ad by Beber Silverstein Group was shot before the 2007-08 season started. That meant there had to be some re-shooting and a little creative editing after Shaquille O’Neal was traded last month to the Phoenix Suns. Watch the ad:
