On The Big Bang Theory episode “The Separation Triangulation,” while Sheldon (Jim Parsons) rents his old room back to work, Koothrappali aka Raj (Kunal Nayyar) finds himself in a love triangle. He’s fallen for a gorgeous blonde named Nell but it turns out she’s married and her husband Oliver (guest star Walter Goggins) is — you might say — very upset.
Nell is portrayed by Beth Behrs. She’s best known for her role as rich-girl-turned-poor-girl Caroline in 2 Broke Girls. She’s also recognized for her roles in the films Hello, My Name Is Doris (Brooklyn), and as the voice of PNK Carrie in the animated film Monsters University. Fun fact about Behrs, the UCLA grad is a classically trained singer. The Big Bang Theory airs Thursdays at 8pm on CBS. (Streaming available for 9000+ episodes plus live TV with a CBS All-Access free trial.)
