J.J. Watt's heart is as big as his game.

The Houston Texans star treated firefighters and police officers in Houston to pizza on Tuesday to thank them for their service in a pre-Thanksgiving gesture that's sure to make even Texans haters smile.

One of the firemen tweeted out the letter Watt sent along with the order:

It's hard to read the letter, so here it is for you to enjoy:

HFD & HPD

I just wanted to send y’all a small token of my appreciation for everything you do. My Dad and Uncle were both firefighters, so I spent a lot of time around the firehouse when I was younger and gained a great deal of respect for both firefighters and the police force along the way.

Y’all show up day in and day out, never knowing what the day might hold and never getting enough thanks for what you do, yet you continue to put others before yourselves and save lives because of it.

As athletes, we often get the headlines and big crowds, but just like the men and women in our military, y’all are the ones who truly deserve the credit, appreciation and admiration. I know it’s not much, but please enjoy lunch on me today. Thank you for all that you do!

JJ Watt 99

And that, ladies and gentlemen, is what you call a class act.
