Is this the most inspiring cheerleader ever?

Buckeye, Arizona student Clayton Mueller accepted a challenge by pop star Katy Perry to create a video to prove which school had the best "Roar."

His submission? This beautiful video showcasing one of Verrado High School's most inspiring students. Megan Squire, 17, was born with Down Syndrome, but that didn't stand in the way of her making the school's cheerleading squad.

In an era of bullying, watch and try not to cry as these high schoolers demonstrate their inclusiveness. If that's not school spirit, we don't know what is.
