Watch: Grandmother has priceless reaction to message from Tebow

Sometimes, all it takes is a simple hello to make someone's day.

Tim Tebow was signing autographs during the St. Lucie Mets' game against the Tampa Yankees on Sunday when a fan, Danny Terp, asked if he could send a message to his grandmother, who recently suffered a stroke.

"What's up, Miss Margaret? It's Tim Tebow," he said in the video. "I hope you're having a great day. God bless."

Terp shared a video of his grandmother's reaction on Twitter.

"That's something, to hear him say your name," Margaret said with a big smile on her face.
