THE BIG BANG THEORY: ‘The Donation Oscillation’ Photos

THE BIG BANG THEORY’s Penny (Kaley Cuoco) and Leonard (Johnny Galecki) aren’t exactly on the same page when it comes to whether he should biologically father her ex-boyfriend (and his new wife’s) child.

Check out photos from “The Donation Oscillation”…

CBS’ take on “The Donation Oscillation”: “Penny tries to seduce an abstaining Leonard to ruin his “donation” for her ex-boyfriend, Zack (Brian Thomas Smith), and his wife, Marissa (Lindsey Kraft). Also, Wolowitz, Bernadette, Anu (Rati Gupta) and Koothrappali turn Koothrappali’s canceled bachelor party into a couple’s trip aboard the ‘vomit comet.’ Recurring cast: Keith Carradine; Brian Thomas Smith; Rati Gupta; Lindsey Kraft. Guest star: Eric Nenniger.”
