Howard: Wait. Wait. If it wasn't for Indiana Jones, the ark would never have ended up at the warehouse!
Sheldon: (gasps) That's true! He collected and delivered the ark to the proper authorities for filing.
Raj: Like a hero.
All: Yeah! Right! Yes!
Leonard: Although, technically, Indy was supposed to take the ark to a museum to be studied. He couldn't even get that done.
All: Aww.

Bernadette told me everything. Now you don't get the left or the right.

This is more like Little House of the Preposterous.

Sheldon

That's strange since peanut butter wasn't introduced until the early 1900s. If I knew this show was about time travel, I would have watched it much sooner.

Sheldon

Sheldon: You've spent time with Amy. Can you think of anything she's fond of that has a bunch of flaws she hasn't noticed?
Leonard: I've gotta go.

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!

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.
