Even when it's his day, Bun B thinks of others. Thursday marked Houston's second annual Bernard "Bun B" Freeman Day, as proclaimed by Mayor Annise Parker. Instead of submerging himself in celebratory superfluity, the UGK rapper lent his star power to a much greater cause: children.

"When the mayor awarded me Bun B Day and I stood before city council, I told them that I wanted Bun B Day to be about helping the children of Houston," the Trill OG told MTV News. "I feel that's always been the first priority."

Bun hosted a food drive for the Houston Food Bank ahead of Hunger Action Month in September to "start tearing down these walls that we have in our community and start unifying again as people." Bun said he believes that the lack of unity in communities brings more problematic side effects than just not knowing your neighbor.

"I notice that people live in these apartment buildings and these subdivisions and unless you grew up with people like in the hood, most people don't really know each other," Bun said. "They don't socialize and they don't associate, and we want to stop that. That's why crime has become more and more prevalent because people don't know who's coming in and out of the neighborhood. That's why we have a lot of misidentified people as criminals because people don't even know the children that are their own neighbors. They're calling [the] police on somebody that stays seven blocks away in the same neighborhood. We don't come out and unite as a community anymore."

On hand to assist the revered rap vet were rappers Marcus Manchild and Trae Tha Truth, who just released his latest mixtape, Tha Blackprint.

"It's always good when you get people on our level doing what we can for the community," Trae said. "And it's a good thing that he teamed up with the Houston Food Bank. That's kind of like history for us. He's down on whatever I'm doing for the kids and when I heard about him doing what he's doing for the Houston Food Bank -- and on top of the fact that it's his day -- that's my brother, so I came out to support."

The first anniversary of Bun B Day was just the beginning of many more charitable anniversaries to come for the Professor of Trill. "This is the beginning of me trying to honor that pledge [to the mayor] and the first place that we decided to stop was with the Houston Food Bank because right now they' re focusing on getting the kids good, healthy meals on the weekend," Bun said.

The Houston Food Bank is a new, 308,000 square-foot facility and is the nation's largest Feeding America food bank. Charity-minded Houstonians dropped off various food stuffs and, in return, were treated to a meet and greet with the Port Arthur-bred MC.
