This week's episode of The Big Bang Theory had a very similar theme to last week's: Penny and Leonard fighting.  This time around, Penny and Sheldon were again having jealousy issues over Penny's male friend(s).

This time around, Penny planned to have a guitar-playing ex-boyfriend of hers crash on her couch for a couple weeks.  Leonard, for obvious reasons, was a little jealous she didn't even talk to him about it.

The two ended up in a screaming match reminding Sheldon of his childhood and the two of them had to retrieve him from the comic book store.  So what happened with Penny's musician friend?  Find out in our "The Guitarist Amplification."

While we find the fight realistic and all, we don't necessarily want to see this in our sitcoms, let alone The Big Bang Theory.  If we wanted that we could all just look at our own relationships.

Give us more nerd humor that we crave!  Sheldon can only hold up so much of the episode when it's about Penny and Leonard screaming.  Now for some of the best Big Bang Theory quotes from the episode:

Raj: "Sorry" doesn't make up for the fact that I had to make chicken and rice with this vegan guy! Do you know what vegan chicken and rice is? Rice! | permalink

Sheldon: Leonard, when that woman moved in three years ago, I told you not to talk to her, and now look, we're going to be late to the movies. | permalink

Wolowitz: But if she dumps you, she'll have a new boyfriend by tomorrow morning, and you'll have a new girlfriend when you figure out how to build one. | permalink
