MAYIM CHASES KEN JENNINGS OFF JEOPARDY!

Big Bang geek is now game show's undisputed queen

BIG Bang Theory brainiac Mayim Bialik has finally pushed rival cohost Ken Jennings out of the race for permanent host of Jeopardy! leading the shaken fan favorite to request a six-month leave! "I'm handing the keys back to the talented actor-producer-writer-director (!) @missmayim for a few months," tweets Ken, 48. "We are lucky to have her! Thanks for watching, and I'll be back before the end of the season." And while it seems the path is clear now for Mayim, 46, to grab the reins of full-time hosting duties, vexed viewers are ripping the iconic show for not giving the gig to Ken, who insiders say was legendary host Alex Trebek's preferred choice!

One social media poster writes: "Come on, @ Jeopardy, just give him the job already."
