• Justin Moore wrote this song specifically for his toddler-aged son, Thomas.
  
  That's my boy
  He's a blue chip straight off the blocker
  Jacked up old truck, Kenwood rocker
  Fist sized dent in a football locker
  
  The proud father is reflecting on the person he hopes Thomas becomes.
• When Moore wrote the song for Thomas, he was too young to appreciate it. "My son's not even 2 years old yet, so he won't get it right now," he noted to Billboard. "But that's something I'll be proud to share with him down the road, and he'll have it forever."
• This was written by Moore with producer Jeremy Stover during a last-minute writing session for Late Nights and Longnecks. Late on the penultimate day of recording the album, while sitting in his hot tub, the singer had an idea for a song called "That's My Boy. " Moore and Stover called co-writer Casey Beathard, who joined them early the next morning. They wrote the tune in an hour, dashed to the studio, and spent the rest of the day tracking it.
  
  "The whole thing happened in 12 hours, and that's the first time that ever happened to me," Moore told Taste of Country.
• Thomas has three older sisters, but this is the first time their daddy has specifically written a song for one of his children. Moore is fully aware he'll have to atone for that with his three daughters. He told The Boot he has a tattoo on one arm for his oldest girl, so that could be an option for the other two.
  
  "My wife and I, two years ago, we had our first son. I wrote a song for him about being a dad to a little boy. And so maybe I can get around to either working out and then getting some more tattoos, or writing more songs for the girls. I don't know, but either way, this song is really special to me."
