"Seinfeld" had The Wiz, Houston has Mattress Mack.

Houston furniture salesman Jim "Mattress Mack" McIngvale is a famous sports bettor known for placing huge amounts of money on teams. His latest bet could bring him over $1 million if the 49ers beat the Kansas City Chiefs on Sunday in Super Bowl LIV.

Mattress Mack placed $1 million on the 49ers' +120 money line, meaning he would win $1.2 million if the Vince Lombardi Trophy comes back to the Bay Area.

This might not be good news for 49ers fans, though. He lost $12 million when the Houston Astros lost to the Washington Nationals in the World Series and has lost $2 million betting against the Chiefs this season in the playoffs.

Mattress Mack clearly has money to burn, but 49ers fans hope the third time is the charm for him going against Patrick Mahomes and the Chiefs.
