When you shoot your mouth off, especially on Twitter, it'd help if you knew what, and who, you're talking about. You could catch a lot of hell.

Witness fool radio host Clay Travis, who's known for being purposely outrageous and controversial. Many times, I'll give it to him, he's on the money.

This time, though, he really stepped in it. Here's his misguided Twitter take from a few days ago:

"I find myself rooting for this Mattress Mack guy to lose all of his money because I'm tired of hearing about him. Marketing genius but I want this guy to go bankrupt. I wish he would lose $100 million."

Houston responds

To say he caught some blowback would be putting it mildly. You don't mess with Jim "Mattress Mack" McIngvale in Houston, Texas. (He has reportedly lost millions on betting on the Astros.) Perhaps a friend in the press box should have told him to lay off Mattress Mack. Travis would have been on safer ground attacking Mother's Day or military vets.

Some first responders:

"I know multiple families who lost their homes and belongings during Harvey. He let them sleep on beds in his stores, fed them hot meals and made sure their children had clothes. That's what he's done for this community."

"What the F have you done for yours?"

"It's going to happen to you for wishing it on him."

"Oh, look who has another trash take."

"Do a little research and you might feel differently. Our world needs more Mattress Macks."

"Clay, this ain't it. Mattress Mack is a legend."

"This is the wrong take. One of the biggest philanthropists in Houston."

And the one who said it best:

"You're wishing bankruptcy on the man who bought 100-plus tickets so veterans could go to the World Series, who opened his store to those who needed escape from Hurricane Harvey, regularly supports community charities, provides furniture to families in need. I could go on and on and on. GFY."

(You'll have to google GFY.)
