'Jeopardy!' fans love new guest host David Faber despite not knowing who he is

Kicking off his week as Jeopardy!’s latest guest host on Monday, was CNBC’s David Faber. And even though he spends his time way up the dial as host of the morning talk show, Squawk on the Street, and he's not as well known as some of the other guest hosts, viewers on social media loved him. One person on Twitter said, “He's actually doing the best job yet. Wow. I don't even know who he is.”

But Faber does bring a little bit of past experience to his week-long stint as host, and that’s because he actually competed in the Jeopardy! Power Players Tournament back in 2012, defeating Kareem Abdul jabbar and Fox News’ Dana Perino. He touched on that experience during his intro, and how he was able to learn up close from the man whose shoes everyone is trying to fill.

“I am so excited to be here. As a financial journalist, I live in a world of facts, and what I love is that that's what Jeopardy! is all about,” Faber said. “Having also played as a contestant with Alex (Trebek), I understand just how important it was to him that the players were able to perform at their very best. And I hope and intend to honor that standard as a guest host this week.”
