Big Bang: "Has your relationship reached its inevitable ugly end?"

On Monday's Big Bang Theory, Penny and Leonard have their first really big fight and poor Sheldon is stuck in the middle. Three of the funniest parts of the episode are summarized below.

1) Sheldon hates fighting, mostly because his parents used to fight a lot when he was a child, which made him uncomfortable. In a funny scene, he mimics his mother and father fighting.
2) Sheldon goes to Penny and wants her to apologize because the fight between her and Leonard is making his life unbearable.
3) At the end of the episode, as Penny and Leonard make up, they also have to win back Sheldon so they, in a scene reminiscent of a mother and father handling their child, promise to always love Sheldon and buy him toys to make him forgive them.

This was a funny episode as usual. This show rarely disappoints.
