"Jeopardy!" co-hosts Ken Jennings and Mayim Bialik faced off against each other, along with "Wheel of Fortune" hostess Vanna White, on "Celebrity Wheel of Fortune." In a sneak peek from the upcoming episode obtained by Fox News Digital, the trio were seen attempting to solve a puzzle while competing for charity. "Funny meeting you here?" Bialik guessed incorrectly as her turn ended. Apparently taking a clue from her guess — which was off by one word — Jennings, 48, then called out the right answer, "Fancy meeting you here." "Yeah, that's it!" host Pat Sajak exclaimed as Bialik laughed and doubled over in embarrassment. Jennings took a small bow as he gestured to the "The Big Bang Theory" alum and told her "Thank you!" "They're two hosts but they work together like that," Sajak joked.
