ice cube's a pimp
A while back, University of Colorado students began trying to rally Goodyear into programming "Ice Cube's a Pimp" on their blimp, based on the song "It Was a Good Day" from back in '92. The trade was, they would raise funds for South Central charity, A Place Called Home, if Goodyear agreed to the stunt. And agree they did.
After raising $25,000 (and counting), Goodyear flew the blimp with Ice Cube on board on the anniversary of the fictional "good day."
