It's been a while since i really enjoyed a sitcom like i enjoy this one. I was suprised when i realized that i was laughing all the way through this episode. I must say that this is so far my favorite ep - well written, lot's of great lines and a fantastic ending - drunk Sheldon and Penny's comment "you do your experiments and i do mine". I am happy to see that this series is getting funnier every week. I see that each weeks the characters develop and we have a chance to see something new about each character. This episode had nice balance between different stories - Penny's new job and Raj's newly developed skill to speak to women. I was happy to see that the plot was skillfully divided and each of characters is given a nice story each week. What else can I say - keep up the good work!
