Terrific episode. They basically made a story line out of Sheldon's 'spot'. Despite the studio audience's over enthusiastic 'oh!!' when Penny shot the paint ball into his spot, it was a pretty decent storyline. We get to see Leonard and Penny as friends which showcased the great chemistry they have together
Penny: What are we going to do
Leonard: We. No no. You've had your chance to be we for like a year and a half now. Right now you are you and you are screwed.
The exchange between the two is terrific and Leonard is at his best when he's involved in somebody else's storyline.
Sheldon is hilarious with his 0000. Penny: 000
Sheldon: There's one more 0. Penny: Sit on the couch Sheldon
The fact that he still doesn't like the seat even after it gets clean, is when the show starts to skate on borderline unbelievability. I understand that Sheldon is peculiar and isn't meant to be taken seriously but it almost seems they are sacrificing the rest of the characters to compensate for Sheldon, making it come off as forced.
Howard and Leslie were pretty funny in bed together as they conversed with Howard's mother
Howard's mum: Is she Jewish?
H: Are you Jewish?
That was pretty funny.
Not much Raj today. All in all a pretty good episode
