[first lines]
Penny: You'll never believe what happened to me at work today.
Leonard Hofstadter: Mph?
Penny: This old guy was choking on a spoon and I saved his life.
[she makes a choking sound]
Leonard Hofstadter: You're kidding; did you Heimlich him?
Penny: No, I said "Oh, my God, I think that old guy's choking!" and one of the busboys Heimliched him.
Leonard Hofstadter: You're a hero!

Crazy Credits

CHUCK LORRE PRODUCTIONS, #408 She had a fierce intelligence in her eyes which was not apparent in her behavior or speech. When you looked into those sparkling, bluish-grey orbs, you couldn't help get the impression that she had something clever to say. She did not. And when she favored you with a smile, you got the reassuring feeling that she understood. She didn't. Not a clue. It was only much later you realized that her wry, knowing grin was something she unconsciously did when she was suppressing gas. Oh, and her touch. The way she held your arm, or delicately draped a hand on your shoulder. That simple gesture made you feel loved, made you feel as if the two of you were connected on the most intimate level. Well, turns out, that was just her way of keeping her balance while wearing six inch stiletto heels. And the worst part was, you didn't care. The illusion was good enough. As long as she didn't talk, fart or fall on her ass, you were a happy man. See more »

"The Tangible Affection Proof" is a Valentine's Day treat ep of "The Big Bang Theory"
14 February 2013 | by (Baton Rouge, La.) – See all my reviews

In this special ep of "The Big Bang Theory" which aired and takes place on Valentine's Day: Leonard offers to take Penny to dinner, which she accepts. Howard is on Bernadette's bad side because he plays on his X-box instead of doing household chores when she's working. Raj suggests to Stuart to keep his comic shop open for the night in order to invite other unattached lonely singles for a party. And Sheldon uses his assistant Alex to help find a present for Amy. I'll stop there and just say this was another hilarious ep of "The Big Bang Theory" especially with the way the dinner between Leonard & Penny and Howard & Bernadette goes and the way things end up with Sheldon & Amy. Oh, and Raj also gives an inspiring speech near the end. In short, "The Tangible Affection Proof" is another comedy classic. Highly recommended!
