Not even gunfire can stop Barney.

A kindergarten teacher in Monterrey, Mexico named Martha Rivera Alanis has become a hero after she sang the purple dinosaur's 'If All the Raindrops' while a gang shootout took place outside.

What's even more amazing is Rivera taped the episode and then posted the footage on Facebook. Five people died during the fight. After the incident, she wrote on her Twitter page, "It was very bad, my little ones in the kindergarten were very scared, and I was too! ENOUGH OF THIS!"

Rivera gave a lot of credit to her kids, claiming her students "behaved in the way we had practiced" after participating in drills should something dangerous come to pass near the school.

Rivera's heroics landed her in the spotlight Monday when she was honored by the local government for her "outstanding civic courage."
