A Houston, Texas, furniture store owner has made history for winning the largest sports bet payout ever after the Houston Astros won the World Series Saturday. Jim McIngvale, also known as "Mattress Mack," earned a $75 million payday after the Astros bested the Philadelphia Phillies in six games, the 71-year-old announced in a tweet which showed him holding a suitcase full of money.  In a statement posted to Twitter, McIngvale expressed his gratitude to the city of Houston, the Astros and his wife Linda.  "This last week has been especially… beyond words," he said.  McIngvale said he would use the $75 million to cover the costs of a new promotion at his Houston-area Gallery Furniture stores in which he said anyone who spends $3,000 or more on mattresses would get their entire purchase for free. McIngvale told ESPN last week that he had he put $10 million on the Astros to win the World Series, splitting the bet across different platforms, including $1 million with WynnBET and $3 million
