This week on The  Big Bang Theory, a show that continues to astound me with its pure and simple humor, Leonard’s beautiful girl friend Penny is feeling left out by the group of friends always talking science. Considering Bernadette is now part of the mix, Penny doesn’t like not being able to relate with them. So she employees Sheldon, of all people, to teach her the ins and outs of physics and to be blunt she doesn’t help the reputation of blondes in this episode.

While this is going on, Wolowitz gets very jealous of Leonard when his girlfriend Bernadette shows a lot of interest in Leonard’s work.

In a very comical series of events Wolowitz tells Leonard to basically stay away from his woman. This only makes things worse between him and Bernadette, because now she threatens to break up with him because of the way he is acting. But, everything works out in the end.

Probably the best humor of this The Big Bang Theory episode is Penny’s lesson on learning physics back at Sheldon and Leonard’s apartment . However, Penny does surprises everyone at the end of the episode when she is able to rattle off a very intelligent monologue of about what Leonard is working on.

The Big Bang Theory remains one of the top comedies on TV today and if you missed this episode you simply must go back and check it out.
