Leonard: They weren't boobies. They were muscles. And, the make-up was green, I was pretending to be the Hulk.
Penny: You were wearing her bra.
Leonard: That was to keep my muscles from sagging!

Raj: Wait. How can anyone ruin Raiders? It's perfect.
Sheldon: Yeah, except for the fact that Indiana Jones is completely irrelevant to the story. With or without him the Nazi's find the ark, open it and die.

Penny: Not even the chapter on the breast feeding crisis?
Leonard: It was not a crisis. Apparently, I favored the left one, she got a little lopsided.
Penny: Oh, my God, you still go left!

Penny: Oh, come on. Why? How bad could it be?
Leonard: There-there's chapters about potty training, bed wetting and masturbation. Basically, if something came out of me, she wrote about it!

Penny

Amy: ... if he weren't in the movie, the Nazis would have still found the ark, taken it to the island, opened it up and all died ... just like they did.
Sheldon: [jaw dropped]
Amy: Let me close that for you.

Indiana Jones plays no role in the outcome of the story.

Amy

Amy: When you told me I was going to be "losing my virginity," I didn't think you meant you'd be showing me Raiders of the Lost Ark for the first time.
Sheldon: My apologies. I chose my words poorly. I should have said you were about to have your world rocked on my couch.

Raj: I didn't want anyone to feel bad at the end of the game. Some of those puzzles were really hard. I didn't know who was going to get Penny.
Penny: Run.
Raj: That came out wrong. But you have to admit you had a wonderful time.
Penny: Run to India.

Sheldon: To the planetarium!
Penny: Let's go!
Leonard: To the Tar Pits!
Bernadette: Let's go!
Amy: There's a Neil Diamond concert next month.
Howard: Let's go!

Penny: Oh it's a blowing alley.
Sheldon: Yes. My brain is better than everybody [holds up bowling ball].

So if you want to solve the mystery of who stabbed Koothrappali in the back with the weapon of indifference, it was all of you.

The Big Bang Theory Season 7 Quotes

Howard: There's a party for incoming post-docs tonight. Go to it and meet someone who isn't made of grease or pie.
Raj: You think you're so cool because your wife is a person?

Sheldon: Even the dung beetle chooses to plot its course by using the Milky Way.
Raj: Is that true?
Sheldon: Everything I say is true. Now, of course, the dung beetle also enjoys eating fece, living in feces and making little balls out of feces. So, pick and choose which aspects of its lifestyle you want to embrace.
