James Holzhauer, the professional gambler who has won a total of more than $1.6million over 21 straight episodes of Jeopardy!, says host Alex Trebek isn’t as innocent as he seems.

‘I learned that Alex Trebek has a potty mouth once the cameras aren't recording,’ Holzhauer revealed.

He was answering a question posed by the student newspaper for Shaler Area Middle School in Glenshaw, Pennsylvania.

Holzhauer, the 34-year-old Las Vegas resident, also revealed how he prepared to play Jeopardy!.

‘No one has ever played Jeopardy like I do, but I didn't let that stop me from approaching the game the way I thought I should.’
