Bang, bang, pollo y camarón.

Texans running back Chris Polk uttered his signature phrase (bang, bang, chicken and shrimp), made famous by HBO's 'Hard Knocks', in Spanish on multiple occasions as his outgoing personality was put on full display out in the community on Tuesday night.

Polk, along with members of the Houston Texans Hispanic fan club Toros Bravos and Texans Cheerleaders, spent an evening volunteering at Casa De Esperanza, a safe haven for children in crisis due to abuse, neglect or the effects of HIV, where they helped serve food to families, played with kids, cleaned up flower beds, stained backyard fences, and helped with inflatable games.

"This means the world to me," Polk said. "I'm still a big kid myself. Just to have an impact and meet the kids and see what's going on in the community, it's just wonderful. I definitely will be coming back here to spend time with the kids. They are our future. I'm proud to be part of an organization that is really involved in the community. Putting smiles on these kids' faces, it really goes a long way."

Polk's playful nature was evident from the start. The running back quickly jumped in to play catch and take selfies with the kids. He also signed autographs for a long line of fans.

Casa, which provides residential care and coordinates medical and psychological services according to the needs of each child, began in 1982 and has grown exponentially with the help of Michael Cordúa, the founder and chairman of the board of directors of Cordúa Restaurants.

Cordúa Restaurants has sponsored Casa's Building Hope for Children Gala for 26 consecutive years, providing food, beverages and staff for the event free of charge. The gala has grown from a $75,000-a-year event to one that now annually raises in excess of seven figures.

"Casa De Esperanza is really one of the most amazing opportunities for people to volunteer their time and their resources," Cordúa said. "The Texans recognize the work Casa De Esperanza does and it's something they want to contribute and help with their Texans Care program."

In honor of all his time and effort, Cordúa was honored with the NFL Hispanic Heritage Leadership Award which recognizes the contributions of outstanding Hispanic leaders in each NFL market.
