Live and in Love

I was watching a Duke-Ohio State basketball game a while back, and when it got out of hand (sorry, Duke fans) I decided to see if anything else was on. I'm always up for a repeat of The Big Bang Theory. This particular episode, as you'll notice, is about fighting robots and Wolowitz's "love live." Huh? I'm confused. Is Wolowitz upset because Penny made a live comment about his love? I guess I'll have to tune in to find out.
