In this recent ep of "The Big Bang Theory": A tenured professor has died leaving the position open for Leonard, Sheldon, and Raj. So they all try to suck up to Mrs. Davis. Yes, the same one Sheldon unknowingly offended in a previous episode. Amy offers her services since she's a fellow instructor but Penny has the sex appeal to get the rise out the rest of the elderly male committee. Of course, it's Kripke they're all keeping their eye on...This was another hilarious ep of the show with a welcome return of Regina King as Mrs. Davis. Sheldon is hilariously as clueless as ever but Leonard does some great physical comedy when he tries to exercise on a workout machine next to Mrs. Davis. So on that note, "The Tenure Turbulence" was another very funny ep of "The Big Bang Theory".
