Episode Quotes

Leonard: Is this the stuff you want me to try on?
Penny: No this is the stuff I want you to throw out. Seriously, don't even give it to charity. You won't be helping anyone.

Sheldon: Just the latest copy of Applied Particle Physics Quarterly.
Penny: Oh, you know, that is so weird that yours came and mine didn't.

Leonard: You are not Isaac Newton.
Sheldon: No, no, that's true. Gravity would have been apparent to me without the apple.

Howard: The monster truck is out of Austin, Texas, and the blue Viper is being operated from suburban Tel Aviv.
Sheldon: You may want to put on slacks.
Penny: What? Eww! Stop it! No! Leave me alone.
Leonard:Who's running the red Corvette?
Howard: That would be me!

Leonard: Oh, geez, does this suit really look that bad?
Sheldon: Forget your suit. Look at my arms flailing. I'm like a flamingo on Ritalin.


Leonard finds a letter in the trash that's addressed to him and Sheldon, inviting them to present their research at conference. Sheldon explains he threw the letter away as he has no desire to pander to an unappreciative crowd. Sheldon doesn't want Leonard to present their work either, as he feels the quality of the research is largely down to him. Despite Sheldon's protestations, Leonard decides to present the research.

Penny comes over to help Leonard find a suit for the conference, though she is unimpressed by his wardrobe. Later, when Penny sees Sheldon in the hallway, she tries to talk to him about his disagreement with Leonard but only makes matters worse.

As Leonard gets ready to leave for the conference, he makes a final offer to Sheldon asking him to jointly present the research with him, which Sheldon rejects. At the conference, Leonard holds a Q & A session after his presentation. Sheldon poses a mocking question to Leonard, at which point they start an argument which soon turns physical.

Back at the apartment, Sheldon and Leonard make up, while Howard and Raj arrive to point of a video of their fight was uploaded to YouTube.
