NASHVILLE (WABC) -- Children expect Santa to come bearing gifts, but for one little boy Santa brought the best gift of all.
6-year-old Aaron Williams thought nothing of it when Santa showed up during story time at his school in Tennessee.
That was, until his teacher told him to tug on Santa's beard.
Aaron's dad, Senior Airman Nicholas Williams just wrapped up eight months of a year-long tour of duty in South Korea.
He received a 28-day pass home for the holidays.
