A video published Saturday by Texas pastor David Grisham of "Last Frontier Evangelism" has gone viral showing the pastor telling a group of children waiting to see St. Nick that Santa Claus is not real. 

The incident took place last week at the Amarillo Texas Mall. 

"Kids, there is no such thing as Santa Claus," Grisham told the surprised onlookers. Santa Claus does not exist, the Christmas season is about Jesus... Parents, you need to stop lying to your children." 

While some parents ignored the pastor, one man approached the pastor and said, "shut up." 

But Grisham continued on insisting to the patrons that Santa is not real. 

That's when the man in the video got into an argument with Grisham. 

"I've got my kids over there, we don't need you blabbing whatever the hell you're babbling," the man said. 

Grisham has been in the news before. In 2010, he made headlines for leading a Quran burning as part of a group called "Repent Amarillo."
