When last we tuned into CBS' The Big Bang Theory, Penny and Leonard debated "opening Schrödinger's Box" by embarking on a date. But one kiss later, they were racing off to their dinner reservation. Has this unlikely couple struck a lasting match? "I think it's going to take a lot of mistakes [before that happens]," theorizes Kaley Cuoco in this video. "You've [first] got to mess things up left and right."

Cuoco speculates that Penny and Leonard will remain "friends" and instead date others, but that likely will only stoke the fire 'tween them. "She might get a little jealous!" says the actress.

Watch this video for more on Big Bang and Cuoco's take on the nerds.
