    The Infestation Hypothesis

    This is another good episode of 'The Big Bang Theory'.

    I think the fifth series has started well, and since the fourth it really seems like it has nailed down what makes a successful episode and what the show wants to be its driving forces moving forward.

    It helps that you have an actor as good as Jim Parsons involved, who can take a very simple premise and make it very funny indeed. I really like the Sheldon/Penny relationship as well, and it gets a fair outing here.

    The Raj and Howard 'kissing' scene deserves special mention too, that was great fun. How Johnny Galeki kept a straight face I'll never know.

    On the whole, good fun.

    A Chair Is a Chair Is a Chair

    Leonard is working on a long distance relationship with Priya but it just isn't the same. Sheldon decides to go to Penny's place and wait them out. She has a nice red chair that is very comfortable. Someone left it on the street and she took it. Sheldon, realizing this, goes bananas, assuming it is filled with bacteria and other things. Well done episode. Amy is really great here.
