He's the funniest guy on CNBC. That's not saying too much, but still.
Like at the end of that last segment (there were 2 guys around the table with him) he says to one, "Always a pleasure!" to the other guy he says, "You did... okay."
Then, when the dude looks all sheepish, he slaps him on the shoulder and says, "Only kidding, you did great!"
He's sarcastic. Must be tough to be paired with Maria.
She seems to be the kind that "doesn't get" sarcasm. In other words, she's stupid.
UPDATE: Then there's this... which I missed. Hilarious, but perhaps over the line.
